I love seafood, but I remember those days. My neighborhood was about 60% Catholic when I was small, and it surprised me when, a neighbor girl had to decline our invite for supper because she was only allowed to eat fish on Friday. Fast forward to High School and I had a friend that had to ask about the spaghetti. He's Italian-American, Catholic, and a straight up guy. He didn't want ANY meat, not even the juices from the meatballs in his Spaghetti during Lent. I advised him, even without the meatballs, there was other meat juice in the spaghetti sauce. I knew because when I had to clean the kettle out at the end of shift, I also found several chicken necks put in there for flavor. (now you know what to do with those things)
