Gee I hope not. There are alot of people I'm going to miss seeing if they don't. You're just going to spend a really long time in purgatory :-)
As an aside... Have you ever dealt with the issue (probably not a Catholic/Protestant thing) of (potentially) our loved ones not being there? I mean, does Heaven lose a small bit of perfection for you if your wife or mother or whoever isn't there?
Just wondering. I guess it's kind of like the chocolate & sex story.
