A couple of years ago I got a call from the Heart and Stroke foundation. A lovely man was on the other end, and asked quite apologetically if I would be able to canvass for them that year (in February). The routes were very small, he assured me, and I'd have two whole weeks to get it done, and my own street was available if I'd like to do it.
He must have caught me at a weak moment, because I said yes.
"What?!" he exclaimed, in shock "You'll WILL?!" He must have been having a bad day, because you would have thought I'd just handed an eight-year-old boy his first puppy.
We laughed about that, and he told me the person in charge of my area would be in touch.
A few weeks later I got a phone call, set a date to get my packet and some brief training, and I was "in".
