" She said she couldn't handle it,’ he told me. ‘I’m about to lose my eyesight and she can’t handle it.’

I was thinking about the word handle, and all the unholdable things that get handled. . . .

'Well, to be fair,' I said, 'I mean, she probably can't handle it. Neither can you, but she doesn't have to handle it. And you do.'

'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 a 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 them anyway. That’s what love is. Love is keeping the promises 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. "
