I wonder if it's merely some language or cultural difference, and I don't mean it as a snipe at all, but may I just say - software products have "features", human beings have traits! Maybe it's a confusion based on the fact that human beings as well as traits also do have "features", but that refers to things like having tiny ears.

Having a very strong liking for sitting reading books for long periods is a lovely trait, but it certainly is not a feature (I would say!).
