In our house it is very rare that anyone is at a loss for words.
AK: "I have a new friend in my class."
LP: "What does he look like?"
AK: "He is black..."
LP: "You mean he has brown skin?"
AK: "He is black, he has brown skin, and teeth, and ears, and arms, and hair..."
Not that I am really sure how else AK could have described her friend, but this makes it clears that she doesn't have nearly as many adjectives in her vocabulary as she has body parts.
I was pretty much rendered speechless from the whole conversation.
