I accidentally sneezed on the paper when I turned it in
Was the person you handed the paper to annoyed?
Yes, very annoyed.
I'm not surprised that the person was annoyed, because no one wants to touch something that someone else sneezed on. That's why you should cover your mouth and nose when you sneeze, so you can keep it under control and not potentially make others sick.
Yeah, I realize now it was not okay.
I think you know now how much it is important for germs not to spread. The fact that Coronavirus is still out there is one big reason. Accidents happen though and am sure you will do the right thing next time and cover your mouth and face.
