Fridays Of Penance?

[KarenJoanna]

So I pray the rosary everyday with my mom and I have told her that fridays is a day of penance or abstaining from meat, We ate meat yesterday and the rosary, I think, usually counts as her penance but yesterday we left the rosary for late and so we decided not to do it, a first my mom said so, but then later even after we were going to, I wanted to go to sleep and so decided to skip it. But as I was going to sleep, i remembered that my moms penance is this because she does not do anything else and that I should have reminded her that she needed her penance but it was late and everyone else was in bed already so my anxiety started creeping in whether or not i am in mortal sin. If I had told her, she would have probably said that it's ok, and so on. Now I am so worried.

Forgetting to remind someone else to do their penance is not a sin of grave matter. (I'm not sure if it's even a sin) So this would not be a mortal sin.
