I got a more positive reaction yesterday when I went to drop off donations at Goodwill and my TC's twin pulled up at the same time. As the other driver got out, she was looking quizically over at my TC. As soon as I got out and said "LOOK! Twins" she laughed and said it had caught her attention but she wasn't sure why until I said something. She immediately followed up with "Don't you just love these things!" as she came over to shake my hand. Had to snap a photo.
