Why?

I dated a guy once who told me that he liked his coffee black.
But he hadn't Always liked his coffee black, it was more of a "once you go black you never go back" type of a thing.
I tried it, but I hated it. I need a lil bit of sugar in my coffee.
But for some reason, when I feel a little blue, I drink my coffee black.

Even though I don't like it.
