Tattoo

This woman came up to me in a club and started talking to me. After a while, she saw me looking at a tattoo on her arm which read "1-11-1989".
"Oh, you're looking at my tattoo, " she said. "It's my daughter's date of birth. "
"Ah... " I replied.
"Oh, you're looking at my tattoo, " she said. "It's my daughter's date of birth. "
"Ah... " I replied.
