there's a piece of dirt on your nose

Oh, no, it's snot! Or so the joke goes. And boy, do we have a lot of dirt here! All three of us have colds at the moment. Luckily, Nate's seems to be pretty mild so far, and he's mostly just stuffy. We've learned, however, that he HATES getting his nose wiped with a tissue. In fact, it makes him cry and scream. This seems awfully dramatic to me, to be perfectly honest. But it's the kid's reaction, so what can I do other than wipe away the snot and then the tears (with a clean tissue, of course!)
