Sleepy

I know people who can sleep on any type of public transportation. Buses, planes, backseats of cars and even here on the noisy T in Boston. I've seen them, and I've heard them. Please don't group me into any of these categories. I must say, on those long flights, I do envy those that can make the time 'fly' by snoozing. If I'm not in a book, I'm usually checking out the flight magazines for the second or third time or just idly staring at the seat upholstery patterns. On late night trips back from places like Boston, I feel too guilty to fall asleep while someone else is driving. You would think that falling asleep on this noisy, bouncing, speeding, squealing contraption might be a lost cause, but there they were recently, snoring away, while I hung on for dear life in the packed car, swinging this way and that. I guess, you could say, that sleeping on these things is some sort of art form, and I'm in no shape or form an artisan.
