When I was a younger (Pentecostal) kid in Catholic grade school, I would give up something meaningful, like cookies, chocolate or packaged pastries.
Then in high school, it wasn't as cool to put as much effort into it; but Catholic peer pressure runs deep, so we usually gave up something inconsequential. I always "gave up" smoking. Entirely meaningless, as I was a non-smoker.
I don't really practice "Lenten fasting" anymore. My next door neighbour, however, still gives up beer and alcohol every year. Given that he is a regular drinker, I have always admired this true sacrifice.
How about you
@trr1, are you giving anything up?
