grayscale photography of man's portrait

I met this homeless man in front of the Gießen railway station. I really struggled with myself to ask him for a photo but eventually I’m very happy that I was able to overcome my shyness and take this photo. By that I captured the awesome expression this man has and I noticed that he is actually a really nice guy. From this day on we always had a little chat when we met. Unfortunately I didn’t see him for a longer time now. I really hope he is fine!
