I did not grow up with animals, so I hardly understood “petting” shall I say. Each time I saw people with their pet, cat and dogs mostly, I wondered,” what does that mean?” or ” what is this about?”, questions like that.
Well, recently I realized having and petting those animals were life saving. how? here it goes: I have been socializing with my neighbors, one could say, and I realized most of them (but me) like, actually love, pets. One of my neighbors told me,” do you know what it’s (petting) called?”
“no”
“It’s called love”

Most people do with them as they do with their own children, sometimes more gentle.

Penny is a cat, and Sophia is a dog.One care giver is an old woman who has nervous ticks or reactions with each single word she says, and the other one is a guy who burns alcohol and medicine as his main daily nutrition. In my mind, both animals are helping their care givers to stay alive since the pets are keeping their owners companies as being “loved” by their care givers.
Probably pets bring meannings and purposes to many lives as children do, better to practice messing up pets than humans.
