What are the consequences of brothers and sister constantly fighting?

Life is too short. No one is garunteed a long healthy life either so if something happens than you are going to live with that guilt. it is okay to argue once in a while youv known eachother for so long your bound to get on eachother nerves but let there be times of peace. one of you has to step up and try to make things right

When they grow up and leave home, they will never be friends. It will never be a loving, happy family.

well it turn out for the best........ from fighting, bros and sissies learn alot about themselves and each other, i used to fight physically and mentally with my older brother and befor we knew it we were best friends because i realized all the pros about him and even though we fought constantly in a way it borought us both together because we transfomed that energy by helping each other out with each others problems...its just normal for people to fight with their siblings you just have to figure out when you're going to grow up.

If you mean physically beating each other, the consequences may include a visit from the police. If you mean arguing, chances are that they will have a much better relationship when they get older. My nieces and nephews used to yell the most cruel things to each other. Now that they're older, they are best of friends.

you become dysfunctional and then the next thing you won't see each other for the rest you life.
