I remember getting a masterclass in calm reasonable debate at the tender age of 7 whilst staying with my very very religious protestant, on every church committee, granny
I assume it was an act of rebellion by my mother, mind you, to get me christened Roman Catholic, at least the other granny was happy with that!
Anyway one afternoon just after lunch the doorbell rang and there stood two young American gentlemen with a religious book in their hand and matching name tags. Of course granny being granny, every moment is a teaching moment, invited the gentlemen in. It was dark when they left.
There had been no raised voices, no accusations of one or the other being wrong. Just many many hours of interesting debate and an exchanging of informational leaflets.
Now whilst I don't think granny learnt much that day, after all she could already suck eggs! those two young gentleman did. And I having no skin in the game religion wise learnt a really good lesson in taking the time to listen to the other side opinion.
On the other hand a trip to Tesco with my mother once resulted in the shop assistant in the fruit aisle screaming at my mother because my mother had asked her very politely why the apples were from South Africa? And did they have any from somewhere else as many mother refused to buy them on principle.
A ten minute rant from the assistant ensued with her calling my mother all sorts of things whilst my mother tried to calmly explain the situation as to why she didn't wish to purchase South African apples. Eventually the shop manager arrived and dragged the screaming banshee away!
Two occasions, two differing sets of opinions. Two completely different reactions. Both educational in in very different ways! I know which I preferred though!
