Lost coins
You are sitting there, minding your own business, maybe reading a good scroll describing some of the newest plays that are currently going on in the theatres. While you are sitting there you have forgotten about those few spare Silver penny you got when you paid for that tasty treat at the baker stand this morning and at some point during the read, you need to adjust your position and without your knowledge those spare coins fall out of your pocket and falls down and in between the couch cushions and you dont notice until you a few hours remember the coins and begins to search for them only to end giving up.
Some times later, you need a new couch and decide to split the old one apart, as you do you discover that the couch were a hidden goldmine as several coins over the years have found their way down the endless empty spaces between the cushions.
Best kind of suprise!
