Well, I do love this topic, though I am very mixed about it.
First of all, I am definitely a clean person, and I am polite around people. When I am sick, I do try to stay home. At the same time schools make it tough when you stay home because then you have piles of work to do.... Anyways my point it if your sick (with the flu or something very contagious) STAY HOME
But, when it comes to sneezing (assuming you don't have a tissue on hand, I would rather see you need into you arm, then your hand. Your hand goes on handles, pencils papers other peoples hands, you wave them around everywhere. While your elbow, well it really doesnt. Now im not saying do it when your sick, but we all sneeze once in awhile.
You know what I see all the time in school? I see people just sneeze, not covering there mouth or anything. They just sneeze in the open air. It is so GROSS and Bloody rude. I have yelled at people before because of it. Actually, last week at a chicken show someone sneezed all over there chicken, I was just thinking to myself, well jeez that guy has a brain the size of the chicken he just sneezed all over.
So, i am mixed, but overall, i would rather see a little kid sneeze on there elbow, than me.
