It's human nature to forget things when we get mad, I've experienced it first hand
(This scenario is just in general) When someone starts an argument with you, people (including you) tend to get mad bc they want to defend their point. However, anger causes humans to think irrationally, why? Idk, maybe the extra adrenaline pumping through our system when we get mad
Anywho, when someone is mad, they don't really think much about the rules
