A tiny windmill

I had no idea what to do today.  I wandered around trying to find something tiny, no tiny flowers , its been so hot that even the bugs are hiding, I even looked for a spider.  I was just at a point where I was admitting defeat when I thought about this tiny windmill.  This small piece of delft (I hope I have spelt that correctly ) was bought for me by my Aunty Blanche over 50 years ago.
