Just got back from a bike ride. On the way out I passed through the park - lots of children playing happily with parents watching on. ....and then I saw this lad (about 5-6 years old) wearing a blue tee shirt with parents close by. He had a sullen expression on his face and an angry demeanour. About 10 yards away from where he was were the resident Swans (Mum, Dad and 6 large youngsters) who always spend the evening and the night in the same place and were all relaxing by the pond. Anyway - firstly he picked up this large stick, whirled it round his head and threw it at the Swans, it missed so he went off to find another. When he did find one he advanced on the youngsters and I really thought he was going to hit one of them with it. The male Swan then hissed at him - he hesitated, thought about having a whack at it and wisely decided against it. He then threw the stick into the pond and followed that with a couple of stones. Parents did nothing, said nothing - just let him get on with it. He must be an absolute joy to teach.
