It all started when I was being correctly accused of dropping spent toilet rolls on the floor and not depositing them in the receptacle provided. Looking for a scapegoat, I uttered, "Have you ever considered it could be your sons?" This suggestion was laughed off and I thought it was the end of it.
However, I find out Harrison mentioned this incident to his Nanny the next day. From what I am told, it went a little like this."Daddy said that we drop the toilet rolls on the floor, we don't use that toilet, it was him!"
I'm not sure what the moral of the story is, but I won't be blaming anything on the childen again, at least when I am not 100% sure they are asleep!
