There is a window in the loft of the chimp house that looks out over the driveway. The chimps – Negra, in particular – like this spot because they can see the humans coming and going. When Sarah and I went into the playroom to clean this morning, we were not surprised to find a nest by this window. But with this nest there were just two toys from the dozens of new toys given out at yesterday’s party: a periscope and a pair of binoculars.
