Semper cras
If I ever have a Latin motto -- for a family crest or something (you know, just in case I get knighted) -- that'll be it. Here's my recipe for making sure not to get any work done on a 4-day weekend:
1) On Thursday, think "well, it's Thanksgiving, so there's no need to worry about work today. I still have plenty of time."
2) On Friday, think "well, I've earned a day off, and I still have plenty of time, so I'll worry about it on the weekend proper."
3) On Saturday, get a chance to see three old high school friends, one of who is just visiting for the weekend from Annapolis, one of whom you haven't seen since his recent return from Japan, and one who you have no good excuse for not seeing, but who you haven't seen in a while. Stay up until 6:30 am having fun and reminiscing about old times.
4) On Sunday, wake up feeling absolutely terrible (partly from lack of sleep, and partly from an incipient cold), and have to decline all offers to do something interesting because "I have to work". Sigh.
