Prisons In The Air

We have all heard of castles in the air
No one's mentioned prisons, I really don't think that is fair
Because prisons are much more common, lurking in our minds
We create bars of steel and walls of every kind

Sometimes we try escaping, but we don't have the keys
So desperately through the bars, ourselves we try to squeeze
Oh that is just too difficult, don't get very far
So we just decide to stay put and save ourselves the scars

It's not too bad in prison, when all is said and done
If you try hard enough, you can even have some fun
But I suppose it would be better, better than I could even dream
If the bars that I created of steel, I could turn into ice cream
