Every once in a while — okay, every day — I find a sign that puzzles me. I like puzzles, mostly, but I also like answers. With that in mind, I’m posting four signs, hoping readers will enlighten me. First up:

Does this mean it’s okay to garbage somewhere else?

Another question for another sign-maker:

My first theory about this sign: a “pre-action” is a thought. But then I realized that thinking is itself an action. That put me in chicken-egg territory, wondering which came first, the pre-action or the thought about the pre-action. What do you think? (And while you’re thinking, are you pre-acting?)

One from a beauty salon:

Is there an analog perm? If I go digital, will I have fingers in my hair, and if so, whose?

Last query:

Is there an epidemic of cave-ins caused by sloppy posture? Or is “Do Not Lean” just mean? I’m leaning (pun intended) toward answering yes to the second question and no to the first, but I’m willing to be convinced otherwise.

Explanations welcome.
