I had this problem after the first long sit I did so much so I had to apologise to the owners on their return warning them that I may have inadvertently misappropriated some of their things confessing to a nasty habit of once I have got used to seeing something day in and day out I think it is mine!
Case of mistaken identity
For instance, I really couldn’t remember if the in-situ blender was mine or theirs and which one of the identical self-raising flours I should take with me. So the next sit I did I boxed up the owner’s pantry, laundry and bathroom items and even coat hangers to avoid confusion when I left over what was mine and what was theirs. Trust me, you think you’ll remember but you usually don’t particularly after a lengthy sit. Not being sure is just one more hassle when it comes to moving out time. And it makes you feel like a bit of twit for not remembering!
You also don’t want to find that you have left something behind that is indeed yours particularly if it is not convenient to pop back and retrieve it.
Keep a running list
Another tip is to keep a running list of anything you might have finished so when it comes time to move out you have a ready-to-go shopping list of things you need to replenish.
These tips all result in saving time and with the busy lives we all lead these days, I am all for anything that saves time.
