Be a good example
To me this is what counts more then anything when it comes to being a pedestrian in busy road with high speed traffic. especially in densely populated areas where kids are used to playing on roads and alleys with low traffic. First kids are worse at estimating risks, second they are less aware of their surroundings and third they are harder to spot by drivers. It's important people are mindful of the message they could give by walking through a red light or cross the street somewhere you're officially not allowed.
Anything to lower the price huh, last time i flew ryanair i had to pay more for a 10 kg cabin bag in a closed cabinet than for my body sitting on the seat below it (not really a surprise though, since the advertised price was 23,99€ which obviously isn't enough to pay for my part of the costs. My brother once had a 4-hour flight for 9€ and decided against booking luggage, just kept everything in his coat pockets lol).
