undressed child

I think it happened during my third standard in Holy Angels. That was the time when the four storied building was under construction.
for this purpose there was a water tank. Some wooden logs was floating on the water. Some say the tank was about 4-5 ft. After lunch during interval, we played at the tank by pushing the wooden logs from one side to the other. Suddenly somebody jokingly pushed me and i fell into the water. but some other boy gave me a hand and i was pulled up. I was fully wet. The Head mistress (sister..i don't remember the name) asked me to go with two senior girls, may be in the 9th or 10th std. They undressed me and dried my uniform. after about an hour, i came back dressed with fear in mind.
