Hello friend, this image abounds a lot today despite the new technology, each person in street situation is an unknown, which we can never decipher, so I can see from your good shot that is a very young person, who may have mental problems, here is normal to see these cases, some let themselves help others return again to the street, I can not help but feel sorry to spend the winter on the street, as always your good eye capturing interesting images that lead us to reflect, I ask the almighty that every day more people in this street situation get some shelter where to stay overnight and protect themselves from the cold, greetings friend @cyclamen
