Eggsackly the way I feel about it. There are times when exhaustion hits...and stress...and annoyance...and, and, and. Were it not for my early training in courtesy, I'd snarl like hell at people.

Possibly people like you and I come from another planet. If so, that's where I'd rather be.

(And the reason I don't say "Can I help you?" [which might be less formal] is because of Sister Mary Leona's ruler.)
