Whats the obsession with having pets and controlling other spcies lives?
The same with wanting a relationship, wanting children.
Generally people want to feel needed, want to feel loved, want to feel in control.
There's few people who don't want or care about relationships kids or pets. You won't hear from them because they aren't online trying to get likes and views. They are out their living their life.
The ones you hear from are jaded. They'll be like "I don't want a relationship! I'm happy to be single! I take care of my own bills, I do what I want, go where I want, whenever I want!" Then you find their other video "I was married for 12 years, after the divorce....."
