Not long after I got my own house, when I was twenty-one, I had a call from a Kirby salesman offering to shampoo my chairs for free. I don't know if you know but Kirby is an American brand of vacuum cleaner sold only through very pushy hard-sell door-to-door selling. Basically because they are terrible and murderously expensive and you'd never buy one in a shop.
Being young, poor and having an old three-piece suite I though 'yeah, why not'. I knew the guy would give me the hard sell but I didn't care, I'd get to sit and watch someone else clean my chairs :0)
I actually quite enjoyed it, his sad routine was funny to watch. At one point he handed me the hoover asking me to feel how light it was, after he'd removed every possible part of it so that only the motor was left! Kirby's are actually very heavy, these people must think you're an idiot.
Anyway, I let him dribble on for hours, I wasn't busy, and he finally gave up. Just before he left he asked if I would like to recommend him to someone else. As if! Then I thought, hang on, and sent him to my mother! :0)
Got a phone call a few days later, really funny, she was cracking up! :0)
Mormons always work in pairs, one who's just starting and a more experienced one. They are brainwashed and stick to their script like glue but sometimes you can reason with the less experienced ones. The older one will try to stop you though. I always take their literature and talk to them as I figure it keeps they away from someone else. JW literature is so well produced, it's a shame it's rubbish! What is sad is that they are actually quite right about a lot of the lesser details but get the most important things totally wrong.
