time sucking office

I went into my office today to put some materials together for a seminar I'm teaching next week. I swear, why does it always take twice as long to do anything in the office than you plan? I think there is a time vortex there or something. I rushed home afterwards because I wasn't sure if we were going to Hamamatsu (Hiroshi's home town) tonight or tomorrow. As it was I crashed out again around 8pm. Am I getting old? Why do I keep falling asleep at 8 o'clock in the evening LOL
