First to Go

I see my brother beside me, so tiny and peaceful, my mirror image. Our time together is drawing to a close – I can feel it, there's not enough space for both of us anymore, it's time to leave.
Suddenly terrified, I touch my brother's arm with the tips of my fingers, kiss him lightly – he looks back at me, large eyes blown larger by fear.
Goodbye, brother. I look at him one last time, cocooned in our cosy private sanctuary, and then I'm gone, quickly losing sight of him.
I was born first. My twin brother followed five minutes later.
