When I tell people I don't want kids, the most common responses are: Won't you be lonely? Who will take care of you when you are old?
It seems like to me that a lot of people are having kids just so that somebody can take care of them when they are old. People like that are not very good parents in my experience. And so, even when they are old, their kids barely speak to them and don't take care for them, because they didn't take care of their kids.
I feel like I wouldn't be a very good parent. I value my free time too much and freedom to go whenever and wherever I want.
