On the stump

I love knocking on people's doors because you never know what people will come up with but I wasn't prepared for getting told off on Saturday! The subject of Robert Kilroy Silk came up and I seem to recall groaning (as you do when it comes to RKS).
Sharp retort from constituent, "You should be nice about him. God sends these people to test us"
I am clearly being tested.
OK, wrist duly slapped but how on earth do you record that conversation on the canvass record?
