"Two sides…one side, two side, go Muwa now!" says Grace as she stands on the couch looking out the window at our neighbours house across the street. She wants to go for a trip across the road to stroke their dog Mula. So off we go across the street, first to the one side….no Mula….then to the other…ahh there she is. "Muwa, Muwa!" One stroke and then, "All done! Go home now."
