The time when I have to renew my registration for my car. Of course I got the notice earlier this month, but in my usual style, I would much prefer to renew on the nearly the last hour of the last day that my current registration is still valid. It keeps life exciting (yes, I know I'm lying to myself, work with me). Then I have to print out the handy dandy temp registration to float me until the replacement decals arrive. At this point it's gone beyond being a bad habit. It's more of a tradition.
