In the book The Boy in the Striped Pajamas, what did Bruno believe the place outside his window to be?

Actually, Bruno knew it was not a farm.  Gretel told him
that was a possibility, but they both agreed that there should be cows and pigs and
horses if it was a farm.  If they grew food, the ground would look a lot better.  (page
34) .  It isn't until chapter 19, when Bruno enters the concentration camp that we find
out what he expected to see.  In his imagination he thought that there was going to be a
lot of happy families sitting around in rocking chairs and telling stories about how
things were better in the good ol' days, and how they respected their elders more than
the children of today do.  He thought that the children would be playing with one
another the games that children play: football, hopscotch, and tennis.  He had an image
of a shop in the center of all the huts and maybe a small cafe and some fruit and
vegetable carts like they had in Berlin. (pg 207)  He saw none of
this.
