Who

"Who, do you think, had made a mark to you, and changed the whole you, to be who you are today?" I asked.
He considered for a moment.

"There's a friend of mine back in school days. He's totally changed my perspective with his line of thoughts. He's really nice, and humble. He's made me felt ashamed of myself and by befriending him, I'd promised myself to be a better man from now on.."

I nodded, listening as he droned on.

"And what about you?" He asked back, his eyes were unfocused. Still thinking about the person.

I smiled and answered, "You."

"I was about to say it was you at first, but I thought it was too cheesy."
