Just Happened to me.
Well, if you're a Catholic, you need to go to Church on Sundays on certain occasions & do some things that are similar to School(Homework, Read, etc.).
It's pretty boring. :/
OH I see. Your parents are too tired from working, so you can do whatever you want. And you don't have to deal with your Catholic church school, so you are freed up.
Well enjoy yourself, sir.
I never done that(My mum's church used to, and it was a prostestant one) and it's not limited to Catholics.
I think the phrase is "Sunday School", not "Church School".
Actually, the above does make a good point. When I saw "church school" I thought "being taught school subjects in church". Of course, this concerned me as there would definitely be problems with objectivity in teaching the material lol.
"Church school"?
