I don't care about your square dance.

It shouldn't be your own problem. If so, it should be that you are too introverted. Actually, I used to feel the same way as you. The reason why you feel sorry for cats and dogs is because you think they are vulnerable groups and need your care. Say something you don't like to hear: you may feel that your situation is similar to theirs, and you need other people's attention.

I suppose you are an only child? Only children are more likely to have this phenomenon. I am also an only child. I have been playing alone since I was a child, mostly with the children in the alley. Sometimes I think I'm autistic. But in the future, we still have to go to the society, get in touch with people, or learn to communicate with people. Even if you think you are good alone, learn to get along with others! As for the question of not caring about friends, I take the liberty to ask: do you really regard them as friends in your heart? Just think of them as your companions, okay? People who are with themselves every day are not necessarily friends!
