I observed this scene while I was taking some architecture shots. The old man is not homeless, but obviously old and poor, and alone. He started chatting with the girl’s and you can see the different reactions – eat.listen.watch.ignore. He was very kind and he asked them which of the buildings in the back they like best and why. A cold day in lock-down times.
Sometimes it is difficult to find the right angle. I observed the area for a quite long time and than I felt that this is the perspective which represents the well best. I took this photo in Porto in December 2020.
