My wife says the same about me. Especially when I get into meaningfull discussion. I don't have coversation if I don't think there is a point being made. No small talk. No chit chat. Only platitudes and terms of endearment. They say what you mean. High signal and maximum efficiency.

I used to enjoy telling jokes when I was younger. Not anymore.

The wife and kids still love and adore me so it can't be too bad.
