Lent: when giving up things is right, part 2

When it benefits other people. Giving up getting ratty with your kids (unless they really do deserve it) improves everyone's quality of life. And I love it when people who give up something like chocolate for Lent put the money they'd have spent on the stuff into a pot, so that a good cause can benefit from their abstinene. More power to their proverbial elbows.
