make it clear i fully support?
I assume this is the bit you're having anxiety about, and all you need to do to show you fully support the cause is stand somewhere that's clearly part of the demonstrating group. You don't need a placard or to chant or anything like that, it's as simple as walking up and joining the crowd.
I spent 3 years on the dole and had one actually helpful advisor who helped me in my job search for a few months before he got moved to the back room and I instead got an endless series of random drones who just wanted me to stop collecting dole.
In the end I actually got a job from someone I met while volunteering.
New answer for the specific context:
You did your best with the 2 year old. Toddlers are difficult because they just make noises and expect you to work out what's wrong for them. Small snack and something to drink are always good starting points, followed by a distraction (like the nursery rhymes video) to get their attention off what was upsetting them.
With the 5 year old, you escalated by increasing the punishment to 15 minutes, and now your brother-in-law pushed it back down she knows you can be overruled. Talk to your sister and her husband to make sure you're both clear on what limits your comfortable with and what specific punishments to give for breaching them, in line with what they'd normally give, so you can both be sure you're giving out punishments they feel are appropriate, so there's no room for her to get you overruled - if she goes to her dad you should both be confident he will back you up. She's of an age where she is going to test what rules and limitations really exist, so you need to make sure she's not getting mixed messages about it. You'll have an easier time distracting her with something interesting than telling her not to do stuff.
"Under the hood" refers to the force behind something being hidden or unexpected, literally coming from the engine of a car being hidden from view underneath a large panel called a "hood", meaning it could be a different make or model than the one suggested by the car's exterior.
RT are not hiding their involvement with this article. It is hosted on their website with their branding, suggesting it is their writing. It's Le Monde propaganda under the hood, because Le Monde's article is what this one is based on.
Why am I explaining this? Becuase you are not very intelligent and should feel too embarrassed to share your half baked opinions.
Make sure to use vocabulary they understand, but don't be condescending with it. They'd rather you speak to them like they're older than they are than younger.
Don't be overly restrictive of their freedom, but be clear about the limits and make sure to enforce them. Explain the reasons for the restrictions rather than just telling them they're not allowed and they'll generally listen.
Give them small jobs to make them feel more responsible and patient about other things.
Do your best to answer their questions properly instead of dismissing them, even if the only answer you can give is "I don't know". They'll listen to adults that they feel listen to them.
How do I convince them the robots are in league with the feds
They are nearly 70 so if you can find an analogy to the miner's strike it would help
I was busy keeping track of Black Tentacles and Crushing Despair's effects so I forgot about the second save for creatures who critically fail against Phantasmal Calamity, which could have stopped the two standing PCs from reviving the two downed PCs and led to a complete TPK. Just one of them failing the save would have guaranteed a dead party member, and they only had about a 20% chance each to succeed. After that they would have had to roll a 19 or 20 to escape the illusion thanks to their debuffs, which they'd need to get on their first attempt or lose both of the downed party members.
And now one of my players has pointed out Black Tentacles has been upgraded to Slither in the remaster so they should have been even more killed. With an extra 2d6 damage plus persistent poison every round I could have absolutely tpk'd them. This is so fucking upsetting. They should have all died and had to make new characters and the paladin player forced to write the backstory on why the help he requested took so long to arrive 
i just wanna kill PCs and everyone said this AP would kill loads but I trained my players too well and now I missed my chance to kill them aaaaaaaAAAAAA 
I haven't killed a PC in MONTHS, and the remaster not only stole my kill but taunted me by leaving them on 1 hp. this is bullshit 
The reason stuff gets inflamed and sensitive with soap and water is because it's healing the damage, rather than just destroying everything in the damaged area and hoping it grows back right. Your body will generally do fine if you're young and healthy, but as you get older it becomes more of a risk.
It's not guaranteed to do more harm than good, but because it destroys healthy cells too it creates a risk that just doesn't need to be taken. It's not more effective at preventing infection than soap and water, and it's not as effective as medical super glue for stopping bleeding, so there just isn't a place for it any more.
