There was a nun who ran the preschool I went to as a kid, and you could do what you wanted in the classroom or outside and be as loud as you wanted to; but there was NO talking in the halls or cafeteria or bathrooms!!
One day, Monte (my best pal) and I were getting water in the hall and I looked over and said, "It tastes like metal!" in a VERY quiet whisper, and the nun was right behind us and smacked me across my back with a 12" ruler. I thought I had been shot by a cannon!!
There was another nun who would come in, though, who was SOOO sweet and ended up taking over the preschool after the other one left (way after I graduated from there); but, finally, she ended up going to the missions somewhere I think in S America.
I have no idea of her history after that--BUT!
The nuns and the teachers and everyone was impressed with my spelling and reading abilities at such an early age.
I am, however, unsure of the correct spelling of controversy (it's correct without the "e" before the "y").
