Being a vegetarian is often like a journey down the yellow brick road. It's full of surprises, sometimes unpleasant ones. Take for instance when you're invited to dinner and after enjoying your scrumptious vegetarian green curry, the hostess proudly informs you that she only used prawn paste to flavour the curry.
By then it would be too late to enlighten your hosts that prawn is not vegetarian (especially if you're having dinner at your boss' house!). The lesson you take away from there is to always warn your hosts before hand what exactly vegetarians eat. Granted, things could go awry anyway but at least you know that you did all you could to prevent ingesting a dead animal.
