Unless expressly prohibited by your religion, please remove your headgear while indoors.
Likewise, dark glasses should be removed when speaking to others, whether indoors or outdoors. You appear shifty and untrustworthy when others cannot see your eyes when you speak.
Please do not answer your cell phone at the dinner table, meeting table or generally at any gathering of other folk; if you must, then excuse yourself, and move off out of earshot as swiftly and unobtrusively as possible.
Please use your turn signals. You did pay for them, after all. Especially use them when you are stopped in the left turn lane at a red light–don’t wait for the light to change to green to start indicating your left turn.
Please refrain from hawking and spitting in public.
Please do not inflict your choice of music on anyone else; second-hand music is like second-hand smoke: unwelcome and intrusive.
Please refrain from dressing your pre-pubescent daughter like a whore. There will be plenty of time for her to make her own fashion errors when she gets older.
Enough with the cheap scent, already, Mrs retired businesswoman. I know that your generation tended to use more perfume than is now the norm, but you must know that nearly all doctor’s offices and other professional premises now request clients to refrain from such practices.
Thank you for your consideration.
