"It's generally little things that spoil the picture..."
As a firm rule, a lady never does any of the following in the company of others:
- examine, pick, or bite fingernails
- crack knuckles
- scratch head
- touch nose without a handkerchief or tissue
- bite lips or inside cheek
- play with hair
- tap or click fingernails
- play with jewelry
- pick teeth
Principle: A lady never exhibits unsightly mannerisms.
