The key to my....

well I have absolutely no idea to be brutally honest. Clearly it's been a slow photo day that I have to revert to a Blip of a key but I often look at this on my drawer and for months now have wondered what it is for. Here's a few possibilities

• Shed at our old house
• Quality glove cupboard at work
•. Jess the fat cat's food stash
•. The basement where I'm going to keep Kent the seal
• My hall of residence at Uni some 15 years ago
• 'the key to my heart' as Boyzone once sang
•. The cupboard holding all my Cliff Richard and Bannarama LP's

Still no idea even after writing all the possibilities down
