I don't think my son recognised him, but it's not impossible - he would've seen his face on TV a lot the day before due to news coverage of Karen's funeral. I'm not even sure if he was referring to Borce when he said "look Daddy!", either, but the result of him saying it was me glancing ahead & looking Borce straight in the face.
I agree he can have a stony look come out when on the back foot & no doubt there are other sides to his nature.
SouthAussie makes a very good point that people have different faces for different occasions. In fact that twigged my memory of a post here many months ago from somebody who had either had an Uber ride from Borce, or knew somebody who had & they also said he seemed like a gentle & courteous man.
The face he wears in other situations may well be quite different, but I was quite surprised that he had a friendly and pleasant demeanour when I spoke to him at Highpoint a day after Karen's funeral - with the pressure on him & a tide of public opinion against him, I didn't have expect that. He didn't seem at all perturbed that some random guy was talking to him, nor worried that he might cop a smart alek remark about Karen, or worse.
