what are the ages of you and your siblings?

in all honesty, if your brother is acting in a way you dont like, you should just not be around him. worrying about him and how rude he wants to be is not going to help you with anything that is going on. You should just try and put time and space between the two of you and leave it at that. worry about yourself first..

stick in there, sometimes family can be pains. but that time will pass
