Maybe this isn’t worth a whole new post, but humor me:
Sometimes the guest never introduces their plus one, sometimes they do but only when they first arrive and i’m not good at remembering names just from hearing them once.
I don’t want to assume “and boyfriend” or “and wife” because occasionally it’s a sister or a business partner.
So “…and companion” is my solution and I’m very happy with it.
As in: “Jane and her companion stayed with us for 3 nights. They communicated their travel plans well beforehand, were quiet and easy going guests while here, and followed the house rules. Luckilt, we were able to accommodate a late check out request, and would be happy to host them again in the future.”
For anyone who struggles with remembering unwritten names but strives for accuracy while balancing privacy, this is my current solution that i’m rather proud of.
