I remember putting my T-Pass back in it around the middle of the train ride, and that's it. Yes, I know my bag has loose pockets, but that's why I always have it like on my lap when I'm traveling. We checked the auditorium floor, and the seat of the car, and those are pretty much the only places I'd been since I got off the train, so I imagine it must have exited my possession sometime on the train. Hopefully it just fell out and I'll be able to retrieve it. (Is it bad that I'm most upset about losing my T-Pass? And glad that it's early enough in the month that I can buy a new one?)
So yeah, I have: my phone, my passport, my checkbook. I'm lacking: my debit card, my T-Pass, my Harvard ID [useful primarily for getting into my professors' offices], my Smith ID ... everything else is replacable (library card which number I have memorized -- so it won't get replaced ;) -- new health insurance cards, cash, etc.). Rly hope it shows up at South Station tomorrow morning.
