A puzzling mission

I arrived at Mr Hs flat a couple of minutes early. After a few attempts ringing the bell I gave him a call and he came to the door fresh from a nap! He took me to the garden where he had a few jobs : - cutting the grass - removing some rubbish - putting a foam gum style floor together I started with the grass as that seemed easiest! Once that was done I chucked the rubbish over the back wall and Mr H drove around in his car to take it to the tip. Finally I decided to brave the floor which Mr H had already started and given up on. There was a mix of sizes of tile to start with so once I’d got rid of the small ones it was relatively easy. To our pleasant surprise, there were exactly the right number of tiles and they fitted the decking perfectly!
