Agree with crayola, If you want to do a letter, to make it official and have on file that makes sense, but I think you owe it to them to have a face to face, letting them know how much you care and making it as descent as possible rather than smacking them with a letter tucked in the bag or a surprise e-mail. put yourself in their shoes, treat them well, it will come back to you ten fold.![]()
