Something weird(er) is happening...

Got to the gym, no G, so hopped on the treadmill to warm up. Had a nice long uphill walk, decided I'd had enough... hopped back off, turned around.. there she was! All bundled up in her hoodie from the brrr outdoors... she hung her backpack on the hook by the door, peeled off her hoodie and... WAS DRESSED ALMOST EXACTLY THE SAME AS ME. The only difference.. her shorts had stripes in them, and mine were solid blue. On top - black tank tops. And this was the SECOND time this week. On Monday we showed up in the exact same shirts and similar bottoms. Guess we really are twins.... what could be next?
