In Sister Pearl's flat, I think it was more of keeping her flat in perfect condition, for not having children from other flats that might not respect the neat condition she wanted her flat to remain in.
In a way for us not having friends in was a good idea for us, there was not the chance they would bring any dirt in, accidentally spill the paints we were using or create any extra chores for us.
"Pearl's Palace" was going to stay that way, we did get the odd Sister visit our flat, but I think in the main, most of the adults in Highfield decided that Flat 1 Wakefield, was not for general visiting.
It was her flat and she was going to run it her way.
Her rules never did us any harm, and did teach us if a boundary was set, we were not to cross it.
After all, none of the other children in their flats were as well behaved as we were, in the grounds however it was another matter.
The order of our fear was
God, death and Roycroft in that order
