Eighty-year-old retired tailor, James McKay, spent Saturday night in jail after 31 thirty-year-old Keith Smith over the head 32 his walking stick．McKay's wife, Laurence told us that while McKay is usually a 33 person, he had been 34 to this act of violence by getting wet just once too often． Smith lives above the McKays and it appears that not only is he a keen gardener, he is also a 35 collector. Unfortunately for him, the water he sent over his balcony every day ended up on the McKay's, or too often, on the McKays 36 . “For the last fortnight, since Smith moved into the flat above us, we have hardly dared to go to our37 ,” said Laurence．She added that it wasn't so much the water falling onto their balcony from Smith watering his plant 38 bothered them, it was more the way he cleaned his fish tanks．“We'd be 39 there happily reading our newspapers, when 40 so much water would come from above that we'd be as wet as if we'd 41 with our clothes on! Neither could we get rid of the 42 of fish!” And on Saturday evening it was just too 43. “It was James's birthday,” explained Laurence, “and I'd made him a birthday cake．The candles were a great sight as you can imagine, but James didn't get to blow them out.” 44 , Smith emptied one of his larger tanks over his balcony and both the McKays and the cake were wet 45．Rarely had Laurence seen McKay move so fast．“I couldn't 46 him．He was up there in a flash．It was the fastest I'd seen him move since 1964.” Smith is not going to take things further with the police．He has also promised to change his 47 from now on．And what of James McKay? 48 he left the police station, a large crowd of supporters sang him, “Happy Birthday”．“49 the most exciting birthday 50 !” said the cheerful old man．“The best since my adolescence I'd say!”
