Talking about unsolicited calls, I had the Jerhovah's Witnesses knock on the door a few years back. Conversation went something like:I stopped voting years ago, all have their own agendas and talk a load of crap.
The now Welsh secretary Simon Hart knocked on my front door, he was the local Tory candidate at the time. Labour were in power then and he started slagging them off with how bad the NHS has got etc, little did he know I was just on the other side of 18 months of treatment for cancer plus other operations before that (hernias & knee) and was very happy with the NHS as were other people I know. I let him know and he cut the uninvited call quick and was gone
Now I see him on the news and laugh about that day
Another one turned up the other week and I just said we are not tories here with an angry look and she left pretty quick too (had the hump that day)
Me: Opens door
Them: "What a beautiful day!"
Me: "Well, it was until you turned up."
My 5 year old daughter from behind me: "I believe in cows!"
Me: Closes door
This makes both me and my, now quite a bit older, daughter laugh every time we see a Jerhovah, but I'm sure it'd work with politician's too!
