This guy in a bar notices a woman, always alone, who comes in on a fairly¹ regular basis. After the second week, he made his move.
"No thank you," she said politely." "This may sound rather odd² 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."
