Well, Vingegaard is just from Thy in the north-western part of Jutland, Denmark. The more west and north you come in Jutland, the fewer words people are using when expressing themselves and the fewer emotions they are showing.
This is a generalisation, I know, but nonetheless true.
I have come across a guy from the western part of Jutland, that used 'Hmm' as 'Yes', 'No', 'Thank You', 'I am fine' etc.
A joke in Denmark also goes, that the people in the north-western part of Jutland has killed off the careers of several Stand-up comedians because of their motionless expressions.
It doesn't mean they don't have emotions and personality, they are just more cautious about showing it.
Well, just trying to explain why Vingegaard might come across as a bit stiff.
