Where do you start?
He decided to chuck his wife and 4 year old son in a car and go for a 54 mile drive to "test his eyesight"???
If true, then that is bloody outright dangerous.
His wife rang him to say that she was not well and probably had the virus. So he went home (good decision). But...then, instead of self isolating with her, he went back to work??? Perhaps it was him who passed it on to Boris?
Plenty more holes in his story as well, as you must realise if you had listened to him.
