Airbnb is cracking down on unauthorized parties by using technology to identify guests likely to throw large gatherings, aiming to prevent disruptive events during celebrations like the Fourth of July.
You cannot reasonably be expected to receive uninvited guests particularly after a recent move so there is nothing wrong with accepting the oranges and saying, 'We look forward to being able to have you over when we are unpacked and ready for guests.' Miss Manners is only relieved that your neighbor also had the good manners and situational awareness to leave after 10 minutes.
