When I was little, a friend of the family took me to her Catholic church with her. Never having seen a crucifix before (Jewish here), I thought it was real. Not real, as it 'the statue actually exists for you to look at' but real as in 'it is what it appears to be and it's happening right now' real. I couldn't figure out why someone was suffering horribly and no one was doing anything but celebrating a mass of something.
Then came communion. 'This is my body,' or something like that was said. I asked the family friend if who was talking and she said that it was from Jesus, the person in the front of the room. I thought that the guy in black was cutting parts off from the feet and feeding it to everyone. I asked the family friend if it was because Jesus had been naughty. 'No, he was very, very good' was the response.
Uhhh...'Am I a bad girl?' I asked. 'No, you are a very good girl.'
A few seconds passed while I mulled it over. I ended up screaming bloody murder and ran out of there so fast I almost fell into the thing with the holy water in it.
