People always talk about spooning when cuddling and who is the little spoon and who is the big spoon when in fact a big and little spoon would not fit well together at all - only same size spoons would, amirite?

Huh, but I have bigger and smaller spoons and the smaller spoon does fit with the bigger it just has to be scooted up

Agreed. I never understood the big spoon/little spoon thing.

Inner spoon. Outer spoon.

So what do you propose instead? Concave spoon and convex spoon? Front spoon and back spoon?
