Cranky Complaints-Lady Buys BOOKS! (or tries to)

Am I this kind of person?

There are some people I am surprised and disappointed not to have heard from over the course of the shiva.  One couple in particular who replied to my email but then didn't show up, haven't appeared, sent anything, phoned, said anything.
Death creeps people out, I suppose.
I'm not the best at dealing with it, but I think I have a pretty good track record for showing up at shivas etc.
It is a bit sad that some people don't seem to make an effort.
Though I know I have to be dan l'kaf zechus and realize they must have other stuff going on in their own lives.
