I have a friend, not sure if he has bipolar or not

Sometimes you borrow money from him and you dont return it in 1 day he might cuss at you crazily or yell at you and throw tables, even though he might be just laughing it with you a minute earlier on


Other times he looks normal or pissed, and you dont give him the money after a day, he simply just say return it to me whenever you have it.

Sometimes if you ask him a question he doesnt answer, but he is just stretching or something all normally, not pissed, and you ask him a second time, he yells out "what!?

Basically sometimes you do something and you expect him to get furious but he doesnt

Other times, you just bother him a little and he gets really pissed
even though he was not in a bad mood in the first place

He doesnt get depressed for no reason or excited or happy or any of that stuff


Just from happy to pissed to normal easily
