Hey thanks for sharing, that makes me feel a lot better. I'm glad you were able to square things away with that girl you embarrassed yourself with.
I wish I could say the same for my high school crush (who brought me to this site). I send her 3 love letters in high school, and then I spent two years avoiding her at social events (it's a small community, we all run into each other).
Finally I decided, like you did, that it was time to stop hiding and get things squared away with this girl. Let her know I wasn't the same anymore, that I wasn't obsessed with her anymore.
So I walk up to her on Christmas Eve (2009) and I use a cheesy pickup line for fun. I said, "Hey, do I know you?" with a big grin. She turned around and smiled and said, "No." Then she keeps walking. I can see her and her sister trying to keep from laughing as they walk away. Then I turn to see her mother. "Hi, Merry Christmas." She ignores me and keeps walking.
