My wife. She got certified 19 years after me but then became a bigger SCUBA nut. I encouraged her to be a Rescue Diver, and she encouraged me to become a DM. We both really enjoy it. We're both tips-only volunteer DMs for classes here in Central Texas and barely break even on costs vs tips, but we both love doing it and are both much better divers for having done it. It helps that our instructor is a total hard@$$ and bad@$$ diver, so we went through a lot of constructive criticism.
