Duke is in the office today and he likes to watch out the front door to the courtyard area. He was waiting there when the mailman came and I hear the mailman ask, "can I come in buddy" with Duke wagging. I told the mailman, "just don't make any sudden movements & you'll be fine." He looked at Duke with a little caution, and I said, "Oh, he's fine" I point at my coworker and add, "I just don't want Jenn to bite you." Mailman stares at Jenn & very slowly sets the mail down.
