This guy in a bar notices a woman, always alone, who comes in on a fairly regular basis. After the second week, he made his move.
"No thank you," she said politely." "This may sound rather odd in this day and age, but I'm keeping myself pure until I meet the man I love."
"That must be rather difficult," the man replied.
"Oh, I don't mind too much," she said. "But, it makes my husband pretty upset."
