My SIL sent Christmas cards to two friends on 12/3. She didn't know that both had recently moved but still lived in the same city. Normally USPS just locates the new addresses. Not this time! SIL had the cards returned on 3/3, exactly 3 months later.
This past Saturday, I received one of my brother's packages. He had told me it required a signature. But when I answered the door, the FedEx driver only asked my name, as he moved his finger across his tablet (?)). Later my brother called to say he had received a delivery Email and said it was the first time he'd ever known me to misspell my own name.
