Over lunch yesterday, someone sitting next to me informed us in her general vicinity that one is not to put anything bigger than an elbow in one's ear. While that didn't mean much to me, she said that includes fingers and even q-tips (no, not Q-Tip, the rapper)! So, here I am, thinking, "What's the use of q-tips, anyway?" But I checked the package and, indeed, it proscribes use for inside one's ear canal. Oh well - I mean it's frustrating, because I had gotten used tot he post-shower ritual of wiping inside my ear with a q-tip and feeling cleaner. Alas, life changes.
(Someone else's blog post discusses a similar situation.)
