The past life story

I was buying milk. While I was in the store something hit me. Literally hit me. I turned around. Some teenager was trowing candy bars at me. I was trying to guess why he was doing that. After a moment realised that he wasn't going to stop this nonsense.Well, it wouldn't harm to ask him.

"Why are you doing this? You don't even know me."

"Liar! " he shouted. " I know you well. You killed me in my last life!"

"Sorry, buddy. I don't believe in that.I am pretty sure that I would remember if I killed a person."

He was staring at me.I felt like he wanted me to be dead.

"That is correct but you killed a person in your past life. I remember your eyes and I will never forget them."

I put my sunglasses on.

"Okay. If you are so sure, describe them."

"Excuse me?"

"You said that you would never forget those eyes.Well, describe them."
