Well, I suspect that it's a sad state of affairs that our mailman knows my dogs by first name, but doesn't know my name. In our little town, you have to go into the post office to get your mail. They don't bring it to you.
Often, the packages we get are for Bunny. I'm not sure how she knows that certain ones are for her, but she definitely does. I think she was a little nonplussed by the ones we got the other day. One of them was actually for Blueberry, but one will be coming for Bunny soon.
