The World Dictionary definition of a Zoo is a place where animals live, are bred and exhibited for the public. There is no description or limits of the types of animals, the types of habitates in which the animals are kept.
I have taken to referring to my collection of dog, three kitties and various teenagers as my zoo. My best friend refers to her home with the 4 dogs and 1 kitty plus 2 kids and husband as a zoo. This is a term of affection for our various animals, 2 and 4 legged who share our lives and homes.
So, in a post about Kathy's animals, I referred to her 2 dogs and 2 kitties as a zoo. Well, someone showed her the post and she became upset with my terminology. And because I use the term "zoo" in an affectionate way, I didn't even think about the possibility of offending Kathy with the reference. In fact, I didn't even remember posting it when she confronted me about it. I most certainly didn't intend for it to upset or offend anyone, especially not Kathy.
I don't want to have to worry about offending people when I post things. I don't want to have to worry about mean people poisoning my family against me. I would never publish anything that would intentionally hurt someone I care about.
