I dunno what the nicest thing I've ever done is. I've bought gas for complete strangers a couple of times. I gave a random co-worker a ride home once, even though it was well out of my way. I set up the home network for a Brazilian exchange student and her family, free of charge. I give away most of my old computer parts, and have forgiven the debts people owe me. I built my sister a light box for tracing from scratch for her birthday. I figure that if I'm ever in dire straits, it would be nice to have someone else look out for me. Karma and all that, plus I hate seeing desperation.
