We are at the Arsenal Gates at the end of a shift.
And for anyone who remembers Trafford Park and in particular Metro Vicks, the scene of thousands of workers streaming out of the factory is a reminder of the importance of heavy industry to the livelihoods of millions of people in this country.
It also seems to have been a bewildering one for the young lad who sent the card to his mother after his first day at the Royal Arsenal in Woolwich.
He reassures her he is fine and describes leaving by "the big gat" and comments on the size of the place.
