Miss Manners: Greeting people you never speak to but see all the time

Dear Miss Manners: I frequently attend luncheons at which the entree consists of bagels, lox (smoked salmon) and cream cheese.

Bagels have grown in size substantially since my childhood. Nowadays, a whole bagel is too much for me, so I carefully take one half with the tongs provided. I spread it with cream cheese, then lay a slice or two of lox on top.
