Social Graces?

Where are social graces these days? I sat next to a guy on the train this morning who ate - I kid you not - and entire box of granola bars like a cow chewing cud. When he got to bar number four I was finding it increasing difficult not to turn and clock the guy in the head and yell, "Shut your damn mouth when you chew!" How hard is it to close your mouth when your eating. Our people that oblivious to the noises they make? Even if they are, have they no sense of what makes good manners? I mean the guy was smacking and crunching like cartoon character. Disgusting.

Plus, he didn't even bother to throw the wrappers away. He just left them on the bag shelf in the chair. Rude.

Oh, and he wore white socks with dress shoes. More proof the guy is a social reject.
