Respect your juniors. One day when you're past-it these are the people who are going to whip your arse, sad has-been that you will be. Treat them right and they may just tolerate having you around. Sound like a strange thing to say? Remember when you were a kid trying to explain to your parents how to operate a VCR and thinking "But this is so simple, how can you not get it"? That will be you tomorrow...
