Funny you should talk about school lunch. My Mom used to make my brother and I cream cheese and jelly sandwiches at least twice a week. I always struggled to eat them. When I was older, perhaps in my 30's, I happened to ask her why she did this. She looked at me with the greatest surprise on you face and replied: "I thought you really loved them!" So much for communication............FrankieFaggots. Made by 'Brains' IIRC. Never knew what they were made of, just nasty meatballs.
The words brains and faggot were never a recipe for excitement come dinner time.
Also coleslaw. My late mother (God rest her) decided I liked coleslaw, so made me ham and coleslaw sandwiches everyday for around 5 years of school and early work years. Hot coleslaw soaked into white bread on a summer's day is NOT something I can now contemplate without gagging.
