Oh Dawn, i had forgotten all about the custard and skin!! Haha, vile, vile vile!! I used to try and slide it off to the edge of the dish but i was still made to eat it, couldn't get away with it at Primary School . Had to smile about you burying your sandwiches though.
Charente Maritime, strange choice of sandwiches!! I do remember the custard at Secondary School was the runny kind though, haha .
Thinking back though, i got away with a lot at Secondary, i used to give my dinner to my mates!
