Don't fear the Reaper

I'm looking at an invitation to the birthday celebration of a distant aunt or maybe it's a distant cousin (see, because the key word is "distant"). It's in August, and it will be her 90th. Seems to me you wouldn't want to plan something like that too far ahead. Maybe an hour ahead? Anything over a half-day and you're tempting fate. But on the plus side, the party is taking place at a church. Sooooo... you know... all bases are covered.
