Yeah, that's understandable, I just wanted to mention for the sake of parsing our friend Awoo's tone.

As an aside, Awoo was also right that saying "calm down" is usually a bad strategy for deescalation if they are actually mad at you. Anger tends to come from frustration, i.e. a feeling of helplessness. "Calm down" tends to read as being condescending or dismissive and thereby only agitates people more in such cases. It's my experience that framing it as asking for a favor or suggesting that both of you modulate your tone (not by just saying "let's calm down") can work better because it implies a recognition of agency or equality between you or the other person.

I'm absolutely not good at diplomacy, so take it with a grain of salt, but I felt obligated to suggest an alternative if I'm going to say something is not a good idea.
