When Rory comes into this video, if you decide to watch it, notice how he just sits there and smiles while John is talking. What is he thinking, how chuffed he is to have John explaining his unique garden?
I watched dozens of similar videos on speed X2 (because, frankly, everyone talks too much) but slowed to normal speed for this one. Scenes similar to this occur all the time. I'll be watching a series of videos produced by a specific gardener and then boom, there they are with John and pleased to present him and each tells him the profound affect that he's had on their gardening style. In this video John learns something significant.
