interesting walk

it is still mild. why do I keep putting on a jumper? we met a nice lady with three dogs. they were small and black with flat faces and feisty temperaments. Pluto had fun playing for ten minutes. We walked on and saw a heron on the far bank fishing. I pointed him out to Pluto who looked but didn't appear to see anything. Dogs see in black and white. The Heron was very still. almost like a cardboard cut out. now and then it's neck would slowly lower, still, remain motionless for a few mins then lower again. Pluto was getting bored so we walked on. The Heron was still there on the way back. Now that was a dilemma. Should I walk quietly past and let him fish or make a noise and scare him away so the fish could live another day. I minded my own business and walked on. I had bought Pluto some sausages from a village shop on the way to the river and he enjoyed them in the rear of the car. He likes his sausages.
