+2 on coughing, sneezing without covering mouth.

Also, blowing nose loudly in public (I call it "honking" -- seems like it's just men who are guilty of this). Is that really necessary?? And LOOKING at what comes out; OMG this is so disgusting I can barely stand to think about it.

Yawning loudly. Again, this is almost always men. What IS it with men? It's like everything they do has to be a show with an audience.

CocoaCoily, I'm going to be a crotchety old woman, too. Hell, I think I'm already there.
shoulder-length 3a/b, depending on weather and products (or lack of products!)
