The man taking apart the scaffolding round the corner was whistling Happy Birthday To You at top volume, and I realised I had never heard anyone whistling that tune. It was constant and so repetitive that it caused the cafe owner to rush out and castigate the construction worker with some venom. I must admit that it is a tedious song, but until that moment I had never heard anyone offer it this way. Maybe it was the only song he knew, or maybe it was his fellow worker’s birthday, and I thought if that was the case, it would soon seem like parody and be even more annoying! SC
