My parents have been gone for quite a few years now. I was an only child. And my mother in particular clung to me. I had an opportunity to move out of state to attend school. I took it & only went back for a couple of brief visits.
I don't know why parents seem to feel that their children owe them. It's not like any of us asked to be brought into this world. And it's not our jobs, as offspring, to entertain our parents. It's our jobs, once we become adults, to go out & build lives of our own. And it's up to parents to take care of themselves. At least that's my opinion.
I also feel a twinge of guilt now-&-then for having left my parents behind. But not that much & not that often. What had to be done, had to be done...
