just an ear to listen

Sometime ago I realize how people somehow feel confortable to talk to me about anything. It is not like I am already intimate to them and they already start talking about intimate things. A friend of mine mentioned that he likes me because he feels confortable talking to me. So I started wandering what is so special about the way I am or behave that end up making people confortable. All I could conclude is that I listen and agree and needed, nothing else. I am just an ear to listen to wherever people has to say. It is not easy being that. I never know what can I say to help. Maybe here is another thing, I care. I have a very expressive face and one can see easily what I am feeling. Perhaps the way I look showing care is what makes people feel confortable. Here is one advantage to people that don't know how to continue a conversation like me, one just need to listen and show care and that's enough.
