Laziness Versus Resource Conservation

It’s one thing to be lazy and not do something because you don’t want to. It’s another when doing it out of conserving precious resources, right?

I haven’t been shaving lately. I mean, well, not since Sunday anyway. Yes, I know, it’s bad. The problem is that I only have one razor left and those things are expensive. My husband is actually using his last one so he’ll need me to get those replacements a short while before I need mine. My question to propose is this: Is it simply me being lazy because, well, I dislike shaving, or am I being resource savvy by not doing so when it isn’t required? Perhaps there is a little bit of truth in both.
