This is my small contribution to life.
When you can't find something, like say a pair of nail scissors or the widget that opens that thingy, you might look in ten different places before you find it.
If you are really organised, you put it away again after you've used it.
Where do you put it?
Not where you found it.
Not where you think the proper place is.
Put it back in the first place you looked for it.
Because that's where your mind tells you it will be, so the next time you lose it, that's where you'll look first.
That's Gent's First Law of Putting Things Back.
It's named immodestly because I'd like to be remembered for something. And nobody's ever told me they heard this anywhere else.
