Leaving his mark on the world.

What is it with children, and small animals, that they cannot resist leaving their mark in wet cement!!
I let Jonty out into the garden and he immediately headed for the conservatory footings, which weren't set of course.
So his pawprints are there for ever. 
Maybe we should put a sealed photograph of him next to the prints so that, in thousands of years time, the archaeologists know whose pawprints they are!!
