I was speaking with a friend of mine who is out of town on business. He's staying in the Bay Area for the next three weeks. I've got some vacation time that I've got to use before the end of June, and since he has a spare bed in his hotel room, figured, "This would make an excellent opportunity to head back west, see some friends I haven't seen in years, etc." An excellent confluence of "free hotel crash space", "vacation days to spare", and "holiday weekend" to add to the time-off.
Start looking at the flights ... become completely impressed that somehow I can get award airfare for Memorial Day weekend at this late of notice, start planning it all through... go to tentatively start putting checkmarks on dates in iCal until I see...
6:00 PM ECON 150
... on the dates. At which point I realize, "Oh yeah... if I want to go, I'm going to have cut at least one, probably two class-sessions in a row."
Which, for a half-summer session that only has about a dozen class-sessions to begin with, really isn't going to go over so well with the professor, I suspect. This higher-learning thing can really put a crimp in your social life.
