i was talking to someone yesterday about Lent and she asked if i did the Sunday rule, meaning Sundays are a day off from the lenten sacrifice, i said NO, that's CHEATING, but i have heard people mention such a rule. i think it's bogus though and misses the point of lent. i have no problem going out and eating seafood, but my husband is an extremely picky eater and there would be nothing for him to eat out. i can't even begin to tell you how aberrant he is, he doesn't eat PIZZA [and he's italian...]
I think it matters, even if it's a "free" day. If you're trying to do a mental and physical discipline, looking for loopholes doesn't seem the best way to go about it.
I have had friends whose husbands are "picky eaters" like that, and the kids pick it up from dad; I hope you won't have a problem with that. I'm such a dedicated cook that I don't think I could have married a man who was a picky, non-adventurous eater! His parents obviously tolerated it when he was a kid. :[
I never heard of taking Sunday off until I was an adult. I have heard of taking St. Patrick's day off. I think about giving stuff up each year for lent and then it hits about the same time as my spring allergies. So my focus in Lent is to do some additional prayers, meditations, scripture readings, and corporal works of mercy, etc.
