Even though I'm a Christian, I don't usually observe Lent. It's just not that big a deal to me. Nor do I observe Mardi Gras, either, but that's just personal preference and nothing to do with my religion.
Well, I'm technically a catholic...though I can't stand the church. I stopped giving up stuff for Lent a long time ago; figure I put up with enough crap the rest of the year that I'm not gonna punish myself any further for the next month.
But, if I were to sum up what my Lenten penance was....
