Why don’t you just go back to the piano store and talk to him again? It seems more natural than stalking via Internet. =)
Well, I originally was hoping to find out over facebook if he was single because it would be weird to go back and such if he wasn’t even available. BUT! Since I couldn’t find him (so disappointed in myself, haha) I did actually go back to the store… twice. But neither time was he working. So, I don’t know. I feel like if I pursue this anymore it might actually legitimately be considered stalking, so I’m giving it a rest.
