Last spring, Elizabeth was briefly hospitalized because of an irregular heartbeat. She spent a few days hooked up to machines which recorded what her heart was doing. I was worried and told her so. "Don't be," she said. "It's not like I'm dying or anything."

But she was.

Sometimes, I can hear her voice so clearly, so suddenly, that I can't believe I'll never see her again. How can it be possible that she's gone when I can still hear her?
