Homeless pople have it tough, while they are desperate for food and shelter, one thing they really need but never ask for is someone to talk to and have a conversation with to feel like a human.
One woman found out that hey boyfriend was homeless for a few months in his life after he left home because of his abusive parent. He was fortunate enough to have other family and friends to stay with but he still never held at home. One thing that helped him through it all was having someone to speak to.
Anytime he is on the streets and notices a homeless person, he will sit with them for a while and strike up a conversation, just to make them feel cared for and treated like normal human beings.
