From age 13-18, I was the custodian of this here church. Then and now, they had a 5 day a week, full time nursery school, so there was *always* something to clean up. On Saturdays, they often hosted Indian weddings and other events so I was always setting up tables, taking them down, ,cleaning up floors and such.
I was very lucky. Having all the keys to a building like this, given complete 100% trust as a teenager, and I never abused it
funny thing is, I never thought twice about it at the time. They *probably* kept a discrete eye on me, but if they did, I never once noticed it. Nobody ever asked me pointed questions and I never felt anything but completely trusted to do the right thing.
