Blue sky, no thinking

Had a few things to do, so decided to get things done. 

Got a few miles down the road when I realised I'd set off without an essential document. 

Turned back, got home and explained to Mo that I was a forgetful numpty. This may not have been news to her. 

I then promptly left the house ... and realised that I still hadn't got the thing I'd returned for. 

D'oh.
