I get what you’re saying and agree that children should not be obligated to take care of their aging parents, but I have to agree with the other comment that the post is more about loneliness and your children going no-contact with you, not necessarily them taking care of you.

I live half the world away from my parents, so I literally can’t physically help them with anything. I also don’t send money or help them financially because they were smart enough to save for retirement and never expected their kids to help them. But I keep in touch with them and chat over Signal every couple of months or so.
