Talking to genius, and other nonsequiters

So I think my nephews getting to sophisticated to talk to me. Yesterday I called him up, and in my usual whimsical manner, greeted him with a comical, " how's it going poopy head, usually he finds comments like this immensely humorous, and laughing, tells me how his days been. This time however the response was anything but congenial. After an unnerving twenty seconds of silence, unnerving because with mateo there is no such thing as twenty seconds of silence, I heard, "squirrel," and then another minute of dead air. I guess I'm just not the sort of conversationalist that I thought I was.
