DEAR MISS MANNERS: Is it rude to cash a check before sending a letter of thank you to the person who sent it?
GENTLE READER: When would you have time?
Thank you letters are due the moment a present is received, so how could you get to the bank, or even on line, before you wrote the letter?
And don't tell Miss Manners you can't find a pen. It's right there in your hand, poised to endorse the check.
