He most likely is not sure how else to come up to you and say hi without you maybe freaking out no him or saying somethingnasty but even if you wouldn't the thought might be going through his mind. A lot of guys do not have the courage to talk to a female so they find ways to approach them to get their attention and let them know that they are there. so next time he does that tell him hi and hit him back. if he blushes he might just like you... gl. :)
he would probably feel guilty
I would say yes. Women do the same.
playfully poke him back.. he is flirting with her
Not necessarily. He might just dislike her. But if he's playfully mean, or is sometimes nice- then maybe.
No, it's actually not bad at all! It may mean that the boy likes you a lot! If he keeps playfully teasing you, it would be a good idea to tag along...if you like that boy of course!
You might just be friends- it might not be flirting at all
boys always play with you and try to be cool when they fancy you. so yes he does fancy you.
most likely yes.
giggle. flirt.
Yes :)
How old are you? I mean seriously. And most likely because that is strange.
Is he ticklish? poke him in his ribs or something. Or wiggle your eyebrows at him when you make eye contact...but make sure you laugh after or you might scare him.
