Chalk and Cheese

Try explaining that to a Frenchman.

I know that out tree is a cherry, because it has blossom. Like Dearie (I still think she is Dudley Moore in drag). 

But the tree on the path outside is still as bare as Mother Hubbard's cupboard.

Like my left leg after it was shaved in hospital and the top of my head.

Although the hairs on my left leg have started to grow again.
