*sigh* What do I do?

Just start talking to him and become his friend, and stop staring...I know it seems like a huge deal now (and I'm sure you've heard this before), but in highschool everything seems like a huge deal and it really isn't. You will find this out a few years down the road, I promise! I was the same way in highschool, never talked to the guys I had a crush on because I felt stupid. There is no harm in just trying to be a friend and find out where things go from there.....
