I was with my oldest son recently and he told me this story which I thought was interesting but am finding hard to draw a moral from. I have only been to Felixstowe once. It must have been some time in the nineties and I was there to preach at Bethesda Baptist Church. In the afternoon I went for a walk with a man whose name I do not recall. As we walked near the beach he picked up a brown pebble that had a grain and he told me that it was fossilised wood.
Well, I took the pebble home and showed it to my son and carefully explained how it had been formed (taking a creationist viewpoint). Anyway, he told me that in school the next day he showed it to his teacher and announced to her that it was an original part of Noah's ark! His teacher was very good about it and suggested that may be he had got something wrong, which he clearly had. Perhaps the moral is how easy it is to miscommunicate. I certainly managed to that time and put two people in a rather awkward situation.
