Water bottles are adult sippy cups
I like to think that I carry a water bottle (everywhere), because I have embarked on a singular campaign to save the earth. The reality that I come around to, is that i want my precious devices to remain dry. Sitting here at my desk, a pint glass leers at me with mischievous bubbles from my peripheral. The subconscious worry that comes with an open container, is almost too much to handle. The re-usable bottle is a symbol of resourcefulness. Its an advertising medium. I've used mine as a hammer, in times of despair. It all boils down to the fact, that even as adults...we can't be trusted with a drinking cup. No matter your age or skill level, never forget to keep a lid on it. Go forth proud, with your stainless steel/double walled/bamboo bottomed vessel, and may your gadgets be forever moisture free.
