This is very trival.
Dh sorts out documents as I'm am rubbish at paper work, so why when I ask for a document there is a few questions.
Like tonight :-
Dh where is the paper part of my licence.
Why do you need it?
So I can sort out a replacement
Why do you need a replacement?because as you know I lost my purse.
When was that?
When we was on holiday you was there. So where's the paper part.
Then I get the answer.
