I don't know what those lads thought when I nudged them, but one of them straight away laid into Jake and knocked him right over.
I yelled for Andy to come and help, and he didn't hesitate. He dashed up at once.
He was moving really fast and I don't think he could stop very easily. He has a lot of bulk. So he collided with one of them and that was it. All Hell let loose!
I suppose I should have just let well alone, pulled Jake out of it and left in a hurry. Easy to see after the event!
