Would it be weird or awkward to message a guy on Facebook?

[Stefanie]

So there's this guy that I've always thought was really good looking, and he went to a high school near mine. We became Facebook friends a while ago, but recently he has come to where I work to get food, (he actually came today again), and I have considered messaging him. I'm scared that like he will thinks I'm weird or something, haha but I also don't want to skip out on the opportunity because I'm afraid. I have never had an actually conversation with him. I also don't even know if he knows my name. I'm just scared! Would it be weird? And what should I say?!
