So sorry for that awkward moment. We are lucky to have supportive neighbors but that in turn requires us to do our part.
We used to have the outside lights on a timer so as not to inconvenience our guests with needing to control the lights but that had the unintended consequence of making them think something had gone wrong. We should maybe go back to that and make sure the guests are advised in advance to expect it.
Please accept my apologies for the confrontation, and thank you for reminding us that it is something we need to re-look at. And thank you for your kind words and for allowing us to host you during your visit.
