Young blue tit

Stuck in again today, waiting for news of my car.  It has blown a 2nd turbo just 4 months after it was replaced.  Of course the people who remanufactured the turbo say it is a manufacturing fault, and the garage who fitted it say it wasn't down to them.  Ever played piggy in the middle?   Anyway, after threatening to keep ringing them until I get an answer we've worked out a way forward.  
So while I brooded on that my spirits were lifted by a steady stream of young birds to the feeder, including coal tits, great tits and this blue tit. They seemed oblivious to me sitting on the patio watching them.
