I’ve just experienced such a mood change. Going from being elated that tomorrow I fly to Egypt, to mad enough to spit feathers. The Powers That Be have decreed that since I refuse to fly to Holland on the same evening as I arrive back from Egypt, they’ve booked me on the first flight out on the next morning.
So I get to fly back, unpack, repack, sleep a few hours and head back out to Eindhoven. Furious doesn’t even begin to cover it.
Anyway, it’s nearly the end of my working day, assuming I can get everything finished. I’ll be back in the country late evening of the 22nd and then back out of the country the next morning. I’ll be incommunicado for some time then, but hopefully in a better mood than right now.
