OOOOOOOOOOOOOOOOMMMMMMMMMMMMMMGGGGGGGGG, I can honestly tolerate about anything . . .but seeing a snot hocker than someone has left laying around on the sidewalks, wherever will almost make me throw up every time. I simply cannot stand it. It has to be my #1 pet peeve. People who sniff . . . . for crying out loud, get a hanky or a kleenex or excuse yourself and go blow your nose!!!! There is NO excuse for that.
