When I was a little kid, my best friend down the street came from a strict Catholic family. Sunday School, "CCD" (after school indoctrination), framed pictures of the Pope and our local Cardinal in their house. My parents thankfully did not raise us religious, and as a consequence, the whole idea of religion seemed idiotic to me.
I held some sway over my friend and his sister down the street, and one day I thought it would be funny to convince them to yell over and over "I hate you, God!" out in front of their house
Needless to say, I wasn't allowed around their place for a while...
