Hey, Megan! I only find sneezing gross when a Kleenex is needed and not used. I also find it gross when the person sneezes, uses their hands and then touches stuff. Ugh. Wash your hands already. I don't want your cooties.
Sure, it can be gross sometimes, especially if there is "residue" afterward. But it can also be extremely relieving--a lot of things that are relieving are gross, I've found.
It's not the sneezing itself, but the phlegm that follows.
Gross, no, it's a natural function such as farting, which I find a bit more gross, but hey it's natural.
Only if my denture comes loose and flies off like a cannon ball, or a snapping canine. Boy, I got into trouble the day I bit Mrs Didge on the butt from the other side of the room. >:-/
