I'm always a bit out of sorts the day after travel. When I was in a long-distance relationship, my boyfriend and I were both a bit out of it for the day or two after each weekend of visiting, meaning the next week was always a bit off. Kids always puzzle why adults find travel to be so tiring since you are just sitting there, after all. Being an adult now, so susceptible to these forces, I really have no idea why --- the psychological displacement? different food? lack of real cooked food? --- but travel is tiring.
The out-of-sorts feeling is even worse after an interview: weeks of anticipation, days of preparation, arriving in a new place I've never seen before, two days of being "on", and then suddenly it's over. Like a date, it almost always goes well, and yet you can't assume anything until you have the signed offer letter in your hand. You only need one, and yet since the unexpected can always happen, you have to try others until one finally sticks.
Last night, I was so tired after getting back from my interview that I fell asleep fully dressed with my light on at 8 pm, and woke up at 2 and then 3 am, finally going to bed at 4 or 5 am and waking up at 8, feeling anything but fully rested. The day has somehow just passed, and I would be better off doing errands than attempting to do work. This is how last spring slipped away from me.
