I can't wait...what should I do?

Okay we have a 3 day weekend, and I wanted to tell my crush that i know he likes me. HE blushes..looks at me all the time and everything else. Now, i have to wait 3 days until i see him at school......errr. I am in 7th grade he's in 8th. I have all A's for grades so i'm fine. I don't want to call him, because i never do that...i just hope that he gets on messenger or something. But, what should i Do at school..should i go bye and say hi Jason...or should i say i know who you like and wink???
