why on earth do you act like that😬

you have a very complicated family. 2 older brothers, 2 younger brothers. you never talk to your older ones since it always ends with a violent fight. once just with a "give me the salt", you ended with a scar on your hand. you are quite close to your father and little brothers. a sad episode happened when you were just a kid. your mother cheated on your father...and the worst is you all found out (except your little bros)that one of them is not the son of your father...you've never really forgiven your mother. that is really sad, I understand. your parents are still together, your father seems to have forgiven his wife but...sometimes remind her what she did and makes her cry. a big argument starts and you are the witness. Well, all those things happen to you, you feel down some days and you suffer from that. So now tell me...WHY DO YOU ACT LIKE YOUR MOTHER?? why cheating?? and why dont you accept you are a cheater??😐😐😑
