This lady asked a sincere, simple question -- and no one has given her a civil response. So, she misspelled caterer; big deal. Have any of you ever misspelled a word before?
Somehow, that old maxim "If you can't say something nice; don't say anything at all!" comes to mind.
Now that the hounds have bayed; I pray that someone will come on this discussion and give this lady a civil, polite answer.
By the way, Squirt, I pray you have a beautiful wedding -- and a long, happy, prosperous married life.
God bless, have a wonderful, blessed day,
