I emailed the innkeepers and told them I left nothing
behind
that I know of and the item they sent does not belong to me.
I did mention I was surprised they'd send something without checking first. So I'm wondering if they mailed the boxers to the wrong person.
It seems pointless to send them back to the b&b which I'll do if they want to pay shipping. I haven't examined them that closely but they can't be worth much. But wait, you say, they could be someone's most favorite pair of boxers! Sentimental value and all that.
I have not heard back from the innkeepers.
