I buried my twin sister six months after she found out she had cancer. Her funeral was three months ago. Today is our birthday and it started with delivery of letters from her. It seems she didn't trust me to move on after her death. She knows me too well. But how can I go on when my other half is just...gone? That's not something I can recover from with a snap of my fingers. But I also can't ignore her instructions even though I'd be perfectly content...
