Those jeans

What is a guy meant to do, when a gal says something like "I don't wear underwear, when I wear those jeans". Why would a chic who isn't a [prospective] galfriend offer such information. What are you meant to do with it. You could run with it, but nothing could possibly happen between the two of you. It's probably why she's sharing. So you just stare at her and shake your head, and long for the day you'll see her in those jeans. It's a step in unraveling the mystery though. That's how they manage to fit into those jeans. Part of it anyway. No underwear.
