Is what I dead weird/wrong?

I think that I am attracted to a girl that I don't know and wanted to know if she's with someone or not. So, I contacted her friend that I also don't know writing this message: "Hi
We sometimes see each other in highschool. I would like to ask you a question about one of your friends of yours if you don't mind"
It's been 3 hours and I didn't receive a response. I am afraid that what I did would be labeled as creepy because surely that wasn't my intention.
