▵ HELP!

Hi guys I'm in a bit of a predicament... We have an assessment in English where we have to write a short story with a captivating title. The short story part is done, the title is the problem, I can't think of one!
Here's a little snippet of what I've written. If you guys have any ideas for a title please let me know! Or even if you want the whole thing published, I don't know but I'm not very good at writing so please, you are entitled to your own opinion but keep negative ones to yourself unless its constructive :)

The sound of a gunshot pierced the air around me. It was as if, for a split second, time had stopped. His body froze, struck mid-stride, his hands, limp as he began to fall. I’ll never forget the sound of his head hitting the ground. The crack of his skull as it collided with the concrete. From my position in the bushes, I was unable to move, almost like, I was the one who was shot. I didn’t feel imminent danger, not as I should have, but instead I felt a loss, confusion, at what had happened. The man I had watched, day after day, now gone, without a name, a word or a past in sight. I promised myself something that day, a promise to explore this mans life, what his childhood was like, whether he had a family, loving or un. I would find out why this man would walk everyday, in his soiled grey suit, with hair knotted and shaggy. The man who was always wearing remarkably clean shoes. I would find out, as soon as I could, the man that walked would no longer be left a mystery.

To say he was active was an understatement. Everyday at 6 in the morning, this old man would stumble ‘round the corner wearing a sort of melancholy expression on his face. He was always alone, accompanied only by his sorrow, and all he would do was pace. Back and forth back and forth, up and down the strip of crumbling road which was just visible from beyond my house. Everyone seemed to ignore him now, it was like a routine, a song on repeat, no notice was ever taken of him, and I think he liked it that way. Granted I had no idea where to start with this man, I knew nothing about him, nobody ever had. Maybe this was why I was so intrigued by him, his aura of mystery, his lack of need for anything, to me it didn't seem humanly possible. I felt drawn to him, and I wasn’t sure whether I liked that yet. It soon became obvious I needed to find something he cherished, a clue to his personality, the key to his heart, so what did I do? I started looking.

Many thanks!
