public transportation

I rarely take public transportation, but when I do, there is usually someone coughing behind me. Is that just the nature of public transportation, or do I have a big sign on my back that says "I'm a germaphobe. Cough, sneeze, or do something disgusting behind me?"

backsplash

How dirty is the backsplash from the toilet...?

smart kid

While I was at dinner, I overheard a bit of the conversation at the next table. A child about nine years old or so was flapping his hands around complaining about germs. His mother told him, "You need to have some germs on your hands. Your body needs it." Lies! How dare she tell him lies! :) Good for the kid; not many are so intelligent at such a young age.

a whole pie

Basic courtesy: don't touch my slice of pizza! What gives you the right to expose my slice with the bacteria on your hands!
