Swapsies :-)

Frank has been looking for a second hand fold up bike for on the boat. 
He was on Facebook Marketplace and a man in Burnley had one and wanted to swap with someone for a road bike.
Frank had his road bike in the cellar in tip top condition.
They met halfway and an hour later Frank was home with his new toy!
No money changed hands.

NB i wouldn't let him on the carpet with a bike but the wheels were clean and I hadn't yet hoovered anyway ;-)
