My prediction about the missing lancet device:
It got put in a safe place, and the item took itself on a vacation somewhere. It will be found later when you're looking for something else.
In my house, the words "it got put in a safe place" mean that you need a bloodhound and a medium with a crystal ball to have a chance of finding it, ever.
There have been things that we have packed, moved, and upacked and they still haven't turned up to this day.
Granted - there have been a few things go missing because the movers did something either careless or nefarious (my Oneida stainless & a new vacuum cleaner in 1998 going from Kentucky to Georgia comes to mind) - but if VorGuy handles the mail, credit cards & other important papers have vanished for days, weeks, months, and in one case, were never seen (by me) again (by him).
He has gotten better about HIS medical devices and the charger for his cell phone, though.
