Everytime when aunt Jocelyn visits the Potters, you can see Mrs. Potter becoming nervous. The reason for this is, that the aunt in her youth spoiled complains the whole day long over the food. "`Marga, where is your home-made jam? From jam bought in a cheap supermarket I get stomach ache."' "`How can you eat these pommes frites swimming in oil? They make you fat."' "`Marga, I have been watching the potatoes boiling for half an hour. Potatoes too long boiled haven't got any vitamines."' "`I saw people die, because they haven't eaten enough vitamines. You don't want loose your aunt, do you? "' "`Aunt Jocelyn usually stays a fortnight and every year the Potters are glad seeing she departing.
