Ok, so this is for my friend.... she's in middle school.

Uhh... so she has this crush on a guy one year level up (different school now, but same primary school). Anyway, so this guy, lets call him JACK, he has a twin brother (not identical)... let's call him LIAM. So Liam is bugging my friend on facebook chat asking if she likes Jack... and she doesn't know what to say.

Oh, and they live down the street from her.... and I'm pretty sure Jack likes her. ..and they're good friends already.

What should she say?

Should she tell Jack that she likes him (in person), or just let things unfold as life goes on?
