Backstabbing sister

What would you do if you had a sister that stabbed you in your back?

Well it depends on the reason and you didn't give one so from what we know You have to think, did she really do it to hurt me or did she do it because she cared and she was looking out for me.

I have 4 sisters and my twin and my 14 year old sister betrays me everyday, now that im use to it, I just dont do anything about it cause I know nothing will ever change them but what I use to do was just have a word with them and tell them how I felt and if they really care about me, they would stop but they never listen so I dont feel loved from them so why bother anymore, right? well, you should talk to your sister and tell her how you feel when she backstabs you.

I think it happens to all but we all get over it in time unless your old enough to know but lucky for me I dont have any sister that I know
