Walk of shame nooo problem and I can do all the variations, from petulent and moody through to disgust and disbelief. As a personal favourite and default I opt for dogged resignation with just a hint of truculence (the latter prevents onlookers from feeling the need to console me).
Of course its a tuff trick to pull off to start with but hey, practise makes perfect. Wonder if its on the TP list this year
A NOHD will be published for the DS in due course, till then wear sunnies.
