What adice should I give my friend on a guy?

[Amber]

She's 15 and we're sophomores. she likes a guy in her class but they dont talk in person, they've only small talked on twitter. shes starting to like him more & more each day. he rides her bus, so she sees him 3 times throughout the day. hes the one that comments on her posts on twitter, but he doesnt talk to her at school. should i tell her to talk to him or to wait for him to talk to her? i want to help her but i dont know what to say.

well if they dont talk then it'll be the most awkward relationship ever, they've got to talk.
