is this normal?

ok so im a junior in highschool. and theres this freshmen that is in my orchestra class and ive been trying to talk to him all year but every time i try to talk to him he looks at me compleatly petrified, then starts giggleing histaricly then runs off or attempts too. and i think hes really cute and i just want to talk to him. and everyone is just like hes really shy and stuff and ive never met anyone as shy as him. its come to the point to where i think he actually hates me and now im scared to talk to him because im under the impression that he wants me dead. although my friends say he dosnt hate me at all. but its scary. and im just wondering if its normal for a junior to be this scared of a freshmen? like i dated a freshmen last year too and i wasnt really scared at all, but then again he actually talked to me. and i dont understand what it means when any guy at all just stares at you like there really really really really really really really scared and starts giggleing. it concerns me terribly. but if you have any answers on this at all and if your actually reading this, please give me some advice because i would really like to know.
