my sister turns 18 tomorrow. she was interested in 1 friend and he didn't "seem" interested in her. so she decided to cut her loses and give him space. another boy started flirting with her. then boy 1 started giveing her lots of attention, so now she is "confused".

I'm older than her by enough years so that this is really funny to me, but i am still nervous because i want her to be happy. and also live with a little less fear then i did.
