Our Garden

It was a wonderful sunny Spring-like day, so after riding 115km on his bike, David finally got out to cut the lawn (it has hardly grown all winter). He was sweating away doing the edges when approached by a pair of wandering ladies.
"Your garden is beautiful" - slightly broken English, perhaps German.
"Thank You".
"Your wife is a very clever person."
"Errrr....yes she is" he says, going back to doing the edges.
