The fundamental sense of freedom is freedom from chains, from imprisonment, from enslavement by others. The rest is extension of this sense, or else metaphor. ↗
I used to love to untangle chains when I was a child. I had thin, busy fingers, and I never gave up. Perhaps there was a psychiatric component to my concentration but like much of my psychic damage, this worked to everyone's advantage. ↗
My kind of gay, meeting a woman and falling in love, is a different experience because it wasn't anything about 'Oh, I've always been gay and I'm breaking the chains.' ↗
