Things were suddenly quiet around the house which meant one of the following was happening:
1. G has discovered some candy and is hiding under his train table eating it
or
2. G has found some sort of liquid to squeeze out of a container
#2 it is!
When I listened very closely I followed the "swishing" sound which led me to the side of the house.
Clothes stripped off and bathing in Gilette 'old man smell' shaving cream.
I should have learned from last time...
