Nah, it is an excellent way to further aggravate someone, though...it depends, are they upset at ME?? Because 'calm down' is probably the worst thing to say then...my approach is kinda like...you know how when you are driving on ice and you start to lose control, and they tell you to steer into the direction you're sliding and not against it? Of course you wouldn't know that, Mrs. California 😛 anyway similar theory, it's counterintuitive but you steer into the upset, acknowledge it, understand it, empathize...I'm just naturally calm, even if I'm mad about something I'll recover fast, I won't forget it but I'm not going to be emotional about it
