But when you're an adult, you realize you need a new toothbrush, so you have to make an excursion to the nearest store that sells them, be briefly dazzled by the sheer array of options, gasp in horror as you realize the price of the average toothbrush, then finally select one that's the right size, shape, color, and bristle strength for your oral hygiene needs based on your mouth shape, hand shape, teeth's current condition, age, blood type, astrological sign, and finally personal preference. Then you check out, realizing that all those little things you like to treat yourself to? You're not buying them today. You're buying a fucking toothbrush.
Then you go and buy some booze and porn to remind yourself that being an adult is still worth it. Sure, I may be up one toothbrush, but at WHAT COST?!
