It's akin to these coins we dig up. You see.....they are "lost" intentionally! And....they do *NOT* want to be found! That's why every chance they get, they make a break for it! How many times have you seen a freshly dug coin jump out of your hand and go thru all sorts of gyrations just return to the bottom of the hole again!!?
I mean I've watched with my own eyes, when a coin jumped, rolled along a parking lot for a full 2 minutes and then land right near where it was just dug!!!
I call these coins "professional hiders".
But, it's not just limited to coins!
Be very careful when putting a find, (or a cotter pin), where you want them!! 😉
