How Analogies Can Be Useful

original title: "Let's Pretend..."
Let's pretend I'm in hairdressing school. I'm studying haircutting; it's taught in a separate section of the school from dyeing, and perms, and sets (for the clients who come in every week). I can take a class or two in other sections, but all my hairstyles have to be constructed with scissors. The problem is that I really prefer styles constructed in the perm section. Of course, I can't use hot rollers.
Hm. Maybe I should try to think of a way to use scissors to get perm hairstyles.
(And I didn't see this until my ridiculous analogy because why?)
