It was a rainy day. I stood in front of my friend's grave with the same bouquet of orchids in my hands.

I laid the bouquet in front of the tombstone and prayed for her soul.

Raindrops dripped from my wet clothes as I refused to move away from my friend. But what confused me the most was whether the drops falling on her grave was from the rain or from my tears.

I stood up. There was one last thing that I wanted to say to her. Something that I wasn't able to tell her when she was still alive.

"I'm sorry."
