WoW something happened

It was really weird....

My guy best friend...

He has a younger sister who's 12

She's a lesbian

And she knows I'm Bi

She's a friend of mine....

I sort of began hating her these days

Cause she was being bitchy and rude

But today.....

She kissed me.....

But I don't like her,I like her brother

So yeah..... I really don't know what to do

Sorry for bothering you guys
