I grew up going to Mass on Saturday night, and did the same after I left the house. I would have such a lovely routine Saturday nights, starting off with Mass, then going grocery shopping, and finally eating dinner while watching Britcoms on PBS.
But then I began to wonder why I didn't go on Sundays, especially since I did nothing out of the ordinary to recognize the holiness of the day. Like Marge I began to feel that attending the Saturday vigil was a bit like cheating. So, I transitioned to attending Sunday morning Mass at 8am. I like it because it's less crowded which makes it easier for me to focus. Plus, it's a great way to start off the day!
I will attend the Saturday vigil from time to time when I have family visiting and always feel indulgent when I sleep in the following Sunday!
