On my way back from lunch I walked passed a charity shop and saw a sign in the window. I was going to go in and let them know but at the last moment I wondered a) if they genuinely did think this was the correct spelling and b) what if the illness they are supporting is characterised by learning difficulites (e.g. high correlation with dyslexia). Not wanting to cause any embarassment I left it, after all there are only two days left for it being up. Happy Farthers Day.
