always

"I kept saying 'always' to her today, 'always always always', and she just kept talking over me and not saying it back. It was like I was already gone, you know? 'Always' was a promise! How can you just break the promise?"

"Sometimes people don't understand the promises they're making when they make them," I said.

Isaac shot me a look. "Right, of course. But you keep the promise anyway. That's what love is. Love is keeping the promise anyway. Don't you believe in true love?" 

I didn't answer. I didn't have an answer. But I thought that if true love did exist, that was a pretty good definition of it.
