On my way to work this morning I walked behind a suited businessman carrying his bagged lunch. What made him particularly unique was that he was carrying his lunch in a white Glad Force-Flex garbage bag: red ties at the top and all.

Through the plastic I could make out his yogurt, hostess cupcakes, and a drink.

It is so hard for me to understand why people drink on the commuter train in the evenings. That might sound strange coming from me, as I quite enjoy a cold beer or glass of wine after work, but I just don't understand why people can't wait until they get home. You might be surprised at how many people imbibe on the train - and how varied the drinkers are. I've seen middle-aged business men with a brown-bagged can of beer, 40-something women chugging bud lights, and even grandmothers sipping pre-mixed margaritas...very strange.
