When my son was 3 or 4 , he rushed to tell me that he had got a Boots Vulture (voucher) from Granny!! I loved the idea of the vultures sat along the top of the cash register!! So we always have "vultures" that provide babysitting or make up!. Another time my son had been talking about pets at school and his friends. We were eating fish and chips , and he said "please pass the guinea pig "(vinegar!) . There are many highly amusing things that I heard or read from junior school children that I taught. Their parents would have blushed to know just how much I was told about what they wore (or not) in bed, or who shouted at who and what did this or that word mean!!! I have been seriously informed by a 7 year old , that it is best not to answer the door to x or y, but if you have to its best if the 10 year old answers and says that Mummy is out at the moment!!
