Well it's annoying, there is some stuff that she shouldn't know about. And I have a mouth like a sailor around
My friends. Don't want to eternally scare her or whatever.
And when I'm with Alec she constantly goes OOOOOOOOHHH, in an annoying manner, which is why I hate 10-12 year olds
Yes, but if you act like you don't want her around, she might think you don't like her:/ maybe you could refrain from swearing when you're around her, and have private time with friends sometime else.
