Amazing Vocabulary

Okay, maybe amazing isn't the right word, but S2 always amazes me with the words he knows and how he chooses to use them. Today S1 was feeling a bit under the weather and was cuddling in my lap, still dressed in his pajamas. S2 comes into the room and looks at us and asks, "Mom, why does S1 have a large hole in his pajamas?" FYI, he was wearing pj's with feet on them and the hole was in the bottom of one of the feet. I said that it was because S1 had just worn them out. I just got a kick out of the fact that S2 would use the word large to describe the hole. Later on I was playing with S1 and discovered that both feet have holes in the bottom, and one is twice the size of the other, hence the need for S2 to say large hole instead of just hole!
