I was hanging out with some acquaintances when I brought up that I had a birthday recently. The woman I was talking to asked how old I was. I told her I was 40 and then braced myself for the inevitable “Dayum, I didn't know you were that old!" reaction I get from people. But instead, she didn't say anything. She just sort of smiled at me and then said (almost to herself), "Wow, so young." Wait, what?
