"All the people like us are we, and everyone else is They ."
Rudyard Kipling

Grandma says

Set a good example

Be polite

Exhibit mercy

Do not lose your temper

Do not interrupt

Do not boast

Do not speak loudly

Respect your elders

Consider others before yourself

Respect the beliefs of others

Be punctual

Do not curse

Do not stare

Do not groom yourself in public

Tip well and discreetly
