With how sad steps, O Moon, thou climb'st the skies! Summary

Imagine a guy staring at the moon. Here's what he says to it: "Hey, Moon, you're looking a little pale there, and you're moving kind of slowly. Is everything okay? It seems to me that you're in love, and it's causing you a lot of pain. I can tell by the way you're moving, and I should know, I feel it too. Hey, just out of curiosity, are the female planets and stars as mean as female women can be? Do they think 'constant love' is a total joke? Do they think being in love is a way of being totally ungrateful? It kind of feels like that that's how they are down there. Just saying." Yup—that pretty much sums the poem up.
