So this was many years ago - my first "boyfriend". Things started out fine, he asked me to some cheesy high-school dance. He seemed relatively normal, a little gawky and strange like a lot of young guys, but nothing extremely abnormal.
After a few months though, he asked me which way my bedroom window faced.
Needless to say, I was highly creeped out and decided that breaking contact was the best route to take. So I did, and he'd hide around corners looking for my friends in case I was with them. His family moved soon after and I didn't have to worry about it anymore. Whew.
