Have you ever lost something that you wanted within a timescale, then thought about the last place you had that something. But it was not there.
Then later found it when you were looking for something else.
I have done this many of a time and I usually think it funny. But for someone who had to have it there and then, it comes off as promiscuous when searching.
This is why when ever you look for something that it is a good idea to make notes of where you placed things.
Finally I have never been one to loose something only to misplace it.
