I believe my father used to be a Bull.
Let me relate an incident. This event happened when I was a kid, may be in Middle school, some 30 years back. One night my Mom asked me to go inform my Dad that dinner was ready, and it was time for him to come home. I inquired where he was and she said that I would find him in a nearby home. We lived in a sub-division and the house where my Dad had been to was a couple of blocks away. I of course always welcomed any breaks that I had to take from doing my homework.
So I went to the neighbor's house and knocked on their door. The husband of the couple opened the door and greeted me. I asked if my Dad was present and he said he was. I told him that my Mom has asked for my Dad to come home. I however couldn't see my Dad in their Drawing room. It seemed the husband was sitting alone in the Drawing room and watching some sports match on TV. It was either Cricket or Soccer, I forget. He wanted me to leave and indicated that my Dad would soon come home after some time. I however was curious to watch the Sports match and hence suggested that I would like to go with my Dad instead. He relented and both of us started watching TV.
After some time the door of their Bedroom opened and the lady of the house first came out. I don't quite remember exactly but I think she looked normal, not disheveled or anything. She seemed pleased and happy and was joking with my Dad. Behind her was my Dad and he was a bit surprised to see me. The lady asked me if I would like to eat or drink something and I declined. Soon me and my Dad went home and the lady saw us off at the door.
They story was they were all friends, husband and wife both, who often got together with my Dad to play cards. That is what my Mom said as well. But now that I think of it, I think there was more to it than just that and I suppose it was a Cuckold relationship.
