This trend, I understand it not

... what? Since when did water bottles become so uncool that it's better to carry entire jugs of water around with you everywhere?

This isn't even jocks on the street - I saw a man last weekend in the Copley Square Starbuck's drinking an expensive latte and taking swigs from a Deer Park gallon of water.

I swear, humanity is fighting civility with every fiber of its being.
