The missing hat by Felix

It was a hot, sunny and windy day so I thought to do some gardening, a couple of hours later, I sat on my bench and in front of me... there was a hat on the table. I was confused because I didn't put it there, so I picked it up and it looked like a very good quality hat and extremely important. I wondered who it belonged to and how it appeared to be here? it must have flown off from someone's head and landed on my garden table, so I decided to keep the hat and wear it.
