Today I was looking for my pot of lip balm, I'd left it on top of the microwave. It wasn't there. I moved everything on the worktop including the microwave moved it all to a different work surface then put the microwave back, the pot of pasta, the whirly thing with knives and the kitchen roll. I put it all back one by one still nothing.
Just dh and I at home, I asked him if he'd seen it he said no. I then started hunting around the kitchen dh came in and pointed to where I had literally just moved everything and said 'is that it' it was on top of the microwave.
A few hours later I needed some Rennie liquid went to the cupboard where it's normally kept it's not there. I took the whole cupboard out gave it a clean and put everything back. Started rooting elsewhere just in case and then I ask dh really exasperated if he'd seen it. He says no, comes in to help me look opens the cupboard I had just cleaned out and says 'it's here' and gives me a 
look.
I asked him if he was messing about even though I knew it wasn't him. So I'm losing my marbles aren't I?!
