H.,
I get the gist of the situation, and I think it's a good thing that you can recognize the changes in your MIL, and it's kind of you to be willing to make adjustments to your schedule to accommodate those changes. It's a very hard thing to come to terms with the limitations of aging parents and the inevitable changes that must be made to family routines.
Regarding the deletion of your post--- The words you wrote are yours. As such, it is my belief that you get to decide what to do with them. If you want to leave your post, fine. If you want to delete it, for whatever reason, that's fine, too. No apologies necessary to anyone.
I don't subscribe to the notion that posts *must* be left up forever simply because it might help someone else or because people took their time to answer.
Others with similar questions can always choose to post their own questions if they don't see one or can't find one like theirs.
Regarding the time people give to answer posts, my thought is when I take time to answer someone's question, that's on me. I make the decision to give my time, and whatever the recipient does with my response, or the question that prompted the response, is their choice.
There are certainly legitimate reasons for people deleting posts, but the reality is you don't have to give a reason.
I realize that my opinion differs from many who get upset when questions are deleted, but I really don't see that the status of someone else's post is any of my business.
