Dear Queenie,
My uncle sent me a generous check for a birthday present, but my dog chewed it up before I could cash it. I told my uncle what happened and he said he would send another check, but he never did.
Queenie, do I still have to send him a thank you note?—Birthday girl
Dear Birthday girl,
Until it is cashed a check is just a piece of paper and your uncle knows you received the original so I do not think you owe him anything more for that.
However, he may have sent a replacement that you never received, so it might be a good idea to ask him about it. If he did, he should know you never received it and if he meant to but did not, the inquiry would serve as a reminder. But beyond that, do not press the issue.
