Please accept my apologies as I will not be able to attend your yogurt class. This is because I'm self conscious. I do not wish to appear as if I've just been shampooed by a thousand pigeons with diarrhoea. Also, dependant on the flavour of yogurt, I feel that this time of year may well attract wasps to the sweetness contained therein. Yours Jim. Jim PTL! Skype jim.liddell6
