Why is it that when I meet people through traveling that I don't learn their names?

I hadn't really thought about it until now, but I believe it is because I really have no intention in remembering their first names. Why bother asking it, right?

On one of the flights that Susan and I were on together, Susan Challenged me. She said she was timing me to see how fast I could know where the lady next to us was from.

It was just a matter of seconds before I knew where she was from and many other things.
