I suggest its hoarding pure and simple.
I hoard my thyroid meds...
in my mind - for good reason.
If they'd stay potent
having them in my car
I'd have them there.
When you fear running out
you put it everywhere your hand might be when you do
but if you live with someone else
you need to make sure
you have enough for YOU.
Let them sink.
AS long as you have YOUR preserver.
