A gentleman does not boast about his junk.
Manners are a sensitive awareness of the feelings of others. If you have that awareness, you have good manners, no matter what fork you use.
A lady never asks a gentleman to dance, or to go to supper with her.
The fault of bad taste is usually in over-dressing. Quality not effect, is the standard to seek for.
A gentleman should never take his hat off with a flourish.
To make a pleasant and friendly impression is not alone good manners, but equally good business.
