After visits from Lyzzy and Jim, as well as at least one other person who came, took some items and left while I wasn’t watching, I finally closed my gates.
I’ve ordered some paintings for Lyzzy, and she has done the same for me, so I’ll need to visit her again at some point after they’ve arrived. Sold some fruit to make a bit of money, and bought everything in Nook’s again, before watering my red turnip and visiting a few animals. New dog Goldie has moved out already, which is fine because I only spoke to her (or him) once.
