… and you are sure he’s done something and is lying about it - but you have no proof?
Two boys, the older one has a history of telling porkies when it suits him - to get out of trouble mostly - and the younger one does not. Four ice-creams in the freezer. Two given out by me yesterday, only one left today. I’m almost certain the older one has eaten it but he strenuously denies it. I have no proof at all either way.
WWYD?
