i recently purchased an expensive lens. but, since i have no concept of care, i accidentally spilled tea with milk on it.
to clean it up, i dropped it on the sink and ran it under the tap.
i even placed it on the dish rack to let it drip dry.
but i can't seem to learn from my mistakes, and i accidentally poured starbucks' signature hot chocolate inside its barrel, which boiled all the glass elements. klutz.
