I have one.
When I made the sacrament of my first reconciliation (confession) in second grade, I went into the confessional and sat behind the screen and LIED to the priest about some sin I committed. I told him that I pushed my brother off of our bunk beds. We never even HAD bunk beds. LMAO! I dont think I have ever told anyone that
My penance? 10 hail mary's, 10 our fathers and 5 glory be's. I didnt do those either.
