Bloody Sheets

OK, so I love my husband dearly, but we happen to have different ideas when it comes to "needs" vs. "wants" in household items. Our latest disagreement is over buying new sheets. We currently have two sets: a flannel set for winter, and a cotton set for every other season. Both of these sets we've had for years. My husband, after shaving his ears the other day, recently blood-stained our "every other season" set. This, coupled with the fact that the elastic has pretty much worn out around the bottom sheet makes me feel that it's time to buy new sheets. No brainer, right? But my husband insists that the sheets work just fine, and since we're the only ones who will see the bloodstains, who cares. Can you please help me talk some sense into him? Oh yeah, I should mention that this is not a financial issue -- we can totally afford new sheets.
