Light in Time

I went a different way on my walk today. Up the street and down another. Is it the time of day or is it the way the light shines that takes you back in time. A memory you can not pin point when it ever happened but a thought comes in from what once was, that will never be again repeated. Even the smell's in the air bring you to that very moment. Maybe even a lot of different moments that intertwine. You just can't remember what it was though that brings you to this place in your thought's. Maybe it is a longing. Could it be longing for someone or to change something that you wish you could, but you can't. I am not sure. It makes you feel lonely even though you know your not alone.
