besides by my parents, I was not spanked by any relatives except for one whackers by a spank-happy aunt (by marriage) who did not like kids being kids as we played running around the house during family reunions in upstate NY during Thanksgiving. She'd use the wooden spoon and catch each of us by the arm as we ran and whacked or butts once. Then the next day she hug us and ask, "are you mad at me for 'spanking' you last night." We'd just say "no" just to get away from her.
I also received a one (maybe two) swatter from her husband (my actual uncle) in the middle of the night. All the cousins slept on the living room floor. While the rest of the cousins slept and in thinking that all the aunts and uncles were asleep, my favorite cousin (girl) and I decided it was a perfect opportunity to play doctor, as we had done earlier that day in the attic of her house.
We were under the sheets, thinking we were "hiding". My uncle (her father) just happened by and delivered a couple swats to each of us and told us to get to sleep. We just giggled about it and lay back down.
I was also paddled by two teachers. One in second grade with a couple of friends. Not sure what we had done.
Another paddling was in fifth grade with the school bully. We both met he in the hall and received three swats each while bent over. I had tapped him on the shoulder for taking too long (against teacher's orders) at the drinking fountain and he turned around an slugged me in the stomach so hard I stooped over.
Then, I got Otk spanked by two different dorm fathers at the boarding school I attended. The first was at age 7 when I was caught playing doctor with the five year old daughter of the school director. The second was for biting the dorm father's son, who never got in trouble for provoking it.
