FLUID ... not a set of rigid rules. Manners change over time & reflect the best practices of our times. Etiquette isn't a set of "prescrip-tions for properness" but merely the guidelines for doing things in ways that make people feel comfortable.
FOR EVERYONE ... not something for the wealthy or wellborn. Etiquette is a code of behavior for people from all walks of life, every socioeconomic group, & of all ages. Good manners are a valuable asset & cost nothing to acquire.
Current... not a thing of the past. The bedrock principles of etiquette remain as solid as they ever were. Manners change over time & across cultural boundaries, but the principles are universal & timeless.
UNPRETENTIOUS... not snobbish. A polite person doesn't try to be someone he's not, nor does he look down on others.
