A crush...or not?

i hv developed a liking 4 this guy at my tuition cl. he isn't gd looking at all (really) and he's weird...the first question he asked me was wether i could flick my toe (whatever that means) i think i got attracted to him when he smiled at me he always does that. but i think he doesn't like me...and i hv no idea why i like him. this is my first crush (besides on my cousins) so gie me some gd advice tho i noe this question is stupid. tks :)
