I'm not one to combine pb and bananas with jelly (Now Nutella! That's another story!) but some friends go together like that, just a little on the edge.
All sandwiches should be bite-sized and heart shaped. As Empress of the Kingdom of Cutesville I proclaim it to be so. Do your best.
Sometimes two people go together so well and yet are just so different that it seems like magic. Some combos are meant to be celebrated!
