Difference Between Boys and Girls

I have been trying to teach my boys to cover their mouths when they sneeze or cough or whatever. One can just never remember no matter how many times I nag him. The other gets it. I was explaining to him this morning that it was great that he is covering his mouth but, if he wanted to keep his hand clean, he could sneeze into the bend of his arm. His response? "Oh, I don't mind it getting on my hands." Sarah's response? "Boys are soooo disgusting!!" I have to agree with her at times like this.:)
