I now judge people based on their parental skills.

You know you're getting old when you start judging people on whether they're good parents.

We had some friends over for lunch last Sunday. We had never met the husband, but afterward we judged him as a cool person and friend-worthy because he was a "good dad."

Before kids, you judge people on their sense of humor or personality or generosity.

After kids, you judge them on what kind of parent they are.

Good parent means good person. Bad parent means bad person. It's a nice, easy way to simply, and it seems intuitively accurate.

If there's someone we don't like, but he or she seems like a good parent we have to qualify our judgement. "I don't like him - but he is a good Dad. So I'll give him that much."
