One time I was leaving the 4th. of July fireworks. I was alone because I went after work. All of a sudden a man ran up to me - completely out of breath - screaming, "WAIT! WAIT!".
I stopped to see what was going on when he caught me and said, "I've been chasing you for two blocks. I saw you and I couldn't let you just walk out of my life without introducing myself."
It was the one time I gave a strange man my phone number...nothing came of it.
