He came here in the first hours of the day to watch the sun climb up into the sky, lighting up the darkness. The cold morning air stung in his lungs and made his warm breath visible in the cold oxygen. He smiled at the light that shined upon his face and closed his eyes so he just could enjoy the moment. The light, fighting the cold air back and warming up his cheeks and lightening up his face to a smile. That was the reason for him to come up this rooftop every day. He just wanted to smile.
