where's my padded cell?

as if what happened earlier today wasn't me being completely brainless, (thinking, of course, that maybe i'm suffering from a lack of caffeine) i just went downstairs to get a diet soda... i put my money in the vending machine, and without thinking i pressed the first button... for a coca-cola classic. i only drink diet soda. i never drink regular soda because it's just too sweet for me, and i especially cannot handle the hefty dose of sugar contained in regular coke. should i call a cab instead of driving myself home at the end of the day? what else could i possibly do wrong today?
