Key

This key is just one small item from the myriad of odd things I have found whilst tidying up my 'miscellaneous' cupboard. I have no idea what it locks/unlocks, where it has come from or whether it still has some function. So, what to do? Throw it away/recycle the metal? Put it in a box labelled miscellaneous and put that in the miscellaneous cupboard? Leave it lying on my desk in the hope I will get a marvelous idea for an artwork?  Mm, you are right it has gone in a box labelled miscellaneous along with a lot of other strange, miscellaneous items and the box has gone in the miscellaneous cupboard. What a hopeless case I am when it comes to decluttering.
