If you do take it/them off... Why? And what do you do with it/them while you're washing your hands?
See, I never do. Only time I take them off is if I'm digging my hands into something grody that will be hard to clean off the rings. My co-worker lost her engagement ring because she left it on the counter and I just observed one of the lawyers in our building pulling all of hers off to wash her hands in the bathroom. Just makes me wonder is all.
