Nice going Saltytri. Those kinds of connections can turn out to be life-changing.
A couple of weeks ago I met and did a minor favour for a chap who builds and installs wardrobes and the like. At the time I asked for some advice about replacing our entry door and sidelight, and he was very helpful. Several days later, out of the blue he rang to say he'd be here on Saturday to help with the job and would not take no for an answer. He drove 3 hours (each way) with a van and tools and we spent a few pleasant hours working on it, sharing a meal and chatting before it was done and he headed home.
He said the best way to repay his kindness was to do something nice for somebody else, and maybe they'd do something nice for the next person, and so on, which would make the world a better place.
It was great. I got a new door, a new determination to help other people, and a new friend.
