There I was - strolling through St Nicholas Fair - when a man in front of me started shouting at someone on his mobile 'phone and waving his arms about. Thumped me hard in the chest - I staggered backward and hit my head on one of the little wooden cabins put up for the fair.
Man - totally embarrassed, apologized profusely and I would have left it at that - but - someone, seeing what happened, summoned up the market supervisor/manager person who, in turn, summoned up a first aid person. They took some convincing that I was completely unhurt - I was wearing a thick coat and a woolly hat so well padded. I was nonplussed and felt a bit sick - but the poor man hadn't done it on purpose.
The market people insisted on taking both of our names/addresses etc before they let us go - in case of repercussions!
