Does this guy like me??help?? flirting? advice? I answer 1 4u?

Well i dont have any classes but gym with him. i sometimes see him in the hallways, always at lunch and in the mornings before school starts. I often catch him staring at me. My friend made me him, and some other kids her "children" so i kinda talk to him a little more but not mucj. one time i was playing volleyball, and he decided to play even tho he sucks at it. he was the only one that laughed at my bad jokes. i dont think he is making an effort to flirt, coz he is shy, but i noticed he stares at me a lot... and is shy near me. normally hes pretty outgoing. I feel like he likes me, unless i am overexaggerating. how can i squeeze into his table w\out bng weird bout it, because i have a feeling heeither likes me, or he knows i lke hm.my othr frnd asked hm if he lked anyone, and he said no(idk if he wud tll my frnd, coz tey dnt rly kno each other) and she said "well someone likes u " and i think he suspects me.we r= popularity and looks i guess. and hes my "brother" so is tat a gud Thng2 Get to kNo hm better
