I like this one guy...?

Well you really wont accomplish much if you just dont talk to him when you see him in a casual day while he is on his bike or w/e just hey him!! if you are near and stops to hey you back ask like .. how you been and aske him bout what he has been up to.. you said he conversed with you alor he probably will make the rest and you just answer if you see a point like you see he still likes you brace yourself ask him for a coffee or hang out movies or w/e you like. only you can do this if you talk cuz he wont know about it by just watching you.
