One of the quickest ways to make a parent feel old? Questions like this one: "Mom? What's a phone booth?"
I feel positively ancient, trying to explain that once upon a time, if someone wanted to make or receive a phone call, they had to stay HOME. There was no carrying a phone with you. And....if they weren't home, they missed the call. Period.
What's something your kid said or did that made you feel old?
