I should preface this story by pointing out that except for last night, when I slept about 7 hours, I'd slept less than 6 hours each night for the past three or four nights, and I don't think I've been eating properly for a few days. So sleep deprivation and a change in diet might explain what's been going on with my brain lately.
I had a weird trip home from work tonight. I left the office about 6:30 and got on a 5 train, which was good because if there was a Yankee game tonight the 4 train would be crowded but the 5 would not. I got out my iPod and put on Bob Dylan's "Bringing It All Back Home," which I haven't listened to in a long time. I was thinking about what I had to do tonight: buy groceries, call a friend who's going to cat-sit for me this weekend, watch some TV, get ready for work tomorrow, talk to Kate, and go to bed early. For some reason I decided to play solitaire on my iPod, something else I haven't done in a long time. I thought I was keeping track of the stops, but I must have been "in the zone" because when I looked up I saw that the next stop was 125th Street, one stop past mine. I still think I was in some sort of time warp, because I've been riding the 4/5 trains for five years and I've missed my stop only once or twice before. I was a little freaked out at my mistake, but I switched tracks at 125th Street and got on a downtown 4 train and got out at 86th Street.
I started walking home when I realized that I had forgotten my Macbook Pro's power supply on my desk at the office. (I realize that I could do without bringing the Mac to work every day, but I have been using it to test the Lotus Notes client for Mac, and it's fun to have at work anyway, so I bring it each day.) I've been making this trip with the Mac since I got it in February, and I hadn't forgotten the power supply before. I was cursing my absent-minded, hunger-addled and sleep-deprived brain when I remembered that I could just buy a spare power supply at Best Buy back at 86th and Lexington. So I turned around and walked back. I had been thinking that I should just get a spare power supply anyway so I wouldn't have to worry about carrying one to work each day, so I didn't really mind paying for another one. When I got to Best Buy I was still thinking about how dumb I was when I realized that I was halfway down the stairs into the subway station again. Now that was me operating on pure muscle memory. I go into that subway station at least once a day on my way to work and sometimes twice if it's a busy travel day, so that's why some part of my animal nervous system ignored my brain and assumed that was where I wanted to go. I turned around again and walked into Best Buy and got my spare power supply.
Three hours later, I feel much better after eating dinner and relaxing. I plan to get more sleep this week and eat right and try to exercise and hopefully that will put things right in my head. It's hard enough to get through my day when my brain is operating at peak efficiency. When I'm suffering from self-induced ADD, I'm not doing myself any favors.
