@futurebird @MCDuncanLab @llewelly Once I hit fourth grade I was responsible for my own lunch.
Things I learned:
You can generally substitute cream cheese for mayo in sandwiches as a bread spread and it's often better.
A sandwich consisting entirely of bread and mayo is not good.
This started because one day I was having trouble finding ingredients and decided to try a sandwich containing only white ingredients: white bread, mayo, and cream cheese. Do not recommend.
A "c" sandwich containing cucumber and cream cheese, on the other hand, is really good.
