Well that brought back memories. No bad stuff while I was there, but it was scary with everyone watching you.
Our church had alcoves on either side of the alter. THere the alterboys could step out of view from the congregation. As Father V. was going through all the stuff before communion, two alter boys on opposites sides, got out their pea shooters and started firing spit wads at each other. Spit wads flying in front of Father V as he was saying the Lond's prayer. Laugh, Laugh, Laugh. Then get serious to ring the bell. Then start the spit wad war all over again.
Father V. was not impressed.
