On my way to work this morning, I was travelling along a shared cycle path. Up ahead about sixty metres away, I observed a man walking his dog. I slowed down and rang my bell - an old style type, not a ping bell - several times in plenty of time for him to react safely. No response. So I yelled 'CYCLIST - !' quite loudly and the man nearly jumped out of his skin. Why - ? 'Cos the dozy sod was wearing earphones; serves him right - !
