What shoud i do?

Well i have a guy friend @ school, well is actually a hi, bye friend because i rarelly see him @ school. But this past saturday he went to my job and so i took his order he came up with some good conversation and he wouldnt leave untill he had to. So this monday i saw him @ school and he said hi and spend about 15 minutes with me. HE AS NEVER DONE THIS I have always tought he was cute and he has a spectacular personality hes a sweetheart but he could be crazy and outgoing but it was suprising because all the girls he dates are bony-skinnny (no offense) and im not skinny but not big at all i have curves, and i was wondering if this are signs of interest. I REALLY HOPE IT IS!!! CAUSE HE IS SO CUTE!!!!!!!!1
