When a jelly vanishes?

Do you ever wish you had said things? Like, asked them how they were more often? Paid more attention to them before they left.

I know this sounds odd, but I do miss so many jellies that have vanished. I wonder if they are okay and if I could have done more to keep them here. Or, just cared more for them. Yes, I know some are just busy, I’m talking about those that just went away sad or upset, or just simply vanished.
