Karen, Brighton UK

Walking my dog in the local park as a group of children and mid teens – all boys – are led in a kick-around on a football pitch. The ‘responsible adult’ in goal yells “Chris, Chris, if you score I’ll buy you a prostitute for your sixteenth birthday!” I’m the only person around and obviously in earshot. As a middle-aged woman I am presumably invisible. To their credit the children do not laugh at this witticism.
