they will forget itMy friend little sister is mad at me need advice from people who have littlke sisters and have advice on this?
Tell the little sister, that you didn't say anything, her older sister knew it all along but didnt say anything.
I think you should forget the both of those immature brats. I mean, do you really want to keep hurting your eyes by reading that writing?
They are both acting immature and need to grow up. I wouldn't to out of my way to talk to either of them. Just wait for them to talk to you. In the future when either of them tell you anything it's best to just keep it to yourself. Don't repeat anything either one of them tell you.
