That's the case with many cryptographic explanations for laypeople, in my experience (as mostly a layperson).

Maybe all these elaborate analogies of Alice walking into a cave and Bob yelling which exit she should come out of, Alice wanting to sell Bob a Hamiltonian cycle trustlessly, Alice and Bob mixing buckets of paint and shipping them via the mail back and forth etc. are working for some people, but it's not me.
