Another old guy and I go fishing together. I try to explain to him that he needs to get in the boat as I back it into the water so that he can use the paddle to push the boat off the trailer. He is frail and afraid to climb into the boat while it is on the trailer so he insists that he'll just stand on the river bank and hold the bow line till the boat comes off the trailer. It never does of course, so I get to remind him every time that 'you can't push a rope!'...Geo
