Here’s some advice about brothers if your an older brother you’ve just got too try too ignore him, I do, but if i’m on edge I try to do something that will calm me down like blare my music, watch my anime, hang out with my friends what ever that takes mind off of it.
If your the younger brother, Your gonna mess with your big brother, but when you do make sure he’s not it a mode, but if you know for sure you did not do anything to piss him off just stay away from him for a while because something probably happened so give him some space. When he’s calmed down he will start making jokes and messing around.
Last but not least if your the middle brother try to be the most calm out of the three you brothers because that way you can handle stuff a little better and you will probably be the mediator a lot of the time and you might find your self restraining one of you brothers. Oh and don’t choose a side just go where facts show if they say that your younger brother is guilty comfort your big brother if he’s willing to talk to you, if your big brother is guilty comfort your little brother, if he’s willing to talk to you.
