Both things you mentioned are about defying expectations - the expectation that your spirit should be as humbled by gravity as your legs, and the expectation that you should make yourself fit into into that infamous "round hole." In short, "you can't make me feel/believe/act that way."

I just had a listen to the tune, and I LIKE it. The last line is a bit hard to figure out how to sing - "In the quiet of the night." The melody is a little quirky, but sounds great that way. I'll take a look at the notation later, just to see how you put the dots down. In any case. quirky is often good.
