Wgat will she think about this letter?

At school I standing in the school store talking to someone. Then this girl came in and she was gorgeous. I can't really explain it, but I wrote her a letter and said that I wasn't at all hitting on her, but I thought she was the most uniquely beautiful girl I had ever seen. I didn't sign a name, and I gave it to the school store to give to her. What do you think she will think? I'm not expecting a relationship with her, I just felt the need to say that to her
