In the children's own words.....
"First confession is when you tell all your sins and Jesus forgives you."
"Confession is like cleaning a window. For every bad thing you do, God drops a bit of dirt on the window. When you do your confession, he cleans the window."
"I wasn't nervous at all when I went up. It was so easy."
"First confession is when you say you're sorry and you receive your first penance."
