Too smart for his stature

My precocious little son never ceases to amaze me. We were up at his school the other day for a party. They have a set of identical twin boys in his class. The teacher was trying to figure out which kid was which and my son chimed in, "Tyler has the oval face and Tanner has the rounder one!" All the mothers were stunned. I was stunned. The twins own mother was stunned! These particular twins are exactly alike! And then I said, "Wow, Ian, how did you come up with that?" And he just replied with, "geez Mom, you aren't very observant are you?!" This of course set the whole room off with laughter and I was as red as a beet. Smartass!
