Are you mocking me Cozy.....
Just seen this. No mate. It's a pack of cards, you keep turning one card after another, looking for the aces. The point I'm making earlier about respect is, that most of the people on this planet are scared of rejection. When we're born, we are automatically scared of loud noises, and falling. As we develop, (well some of us don't, like Hector hasn't) we develop other fears. One of these is rejection, or in this case "no's". So you have a gift of "bottle". A lot of the canvassers on here like Wizz, or Mick Kent have it and earn by using it.
I don't like rejection, but when it comes to knocking doors, I'm not scared, so because I have no fear, I find it easy. So I'm not "brave". People like you are disappointed with a crap result, but kept going for 4 hours!! That's the difference between you and some others.
When you get past this episode, you may want to take up canvassing. Just a thought.
