Many people live a different lifestyle from what you may be used to or believe in. I have found out that by talking with people and letting them speak freely, you can learn a lot about how/what they believe, how they make a living, and many other things. By listening and not judging, you can be one who understands how they may feel they way they do about certain things in life they (or possibly you) may be going through. You may even find you have experienced almost the same circumstances, and just wanted someone to listen. A positive reaction or answer will speak volumes about you and your character.
I recently spoke to someone while waiting for repairs on my vehicle. I found out that they previously lived in the same place I did! Though the conversation I mentioned a belief that I held, and the other person spoke that they did not believe in this manor, and I felt best not to push my belief onto them, and considered their feelings as I would want the same in return. How many times do we try to push our beliefs, onto another just because? How many times when we do this does it leave things on a negative note when we depart from their prescence? I, for one, want to feel that my interaction is a positive one. This means the other doesn't feel any negativity and can feel comfortable the next time we meet or run into one another.
Interacting with family, friends, and even strangers can be, upon departing, a positive or negative. How you interact, what you say (or don't) and even the "vibe" you (or they) give off, means a lot to the other person or people. You want someone to walk away and feel a sense safety that you have not invaded their space, their beliefs, or even them as a person. We are all different and there is no mistaking this fact. Returning to someone you've previously met who gave you a feeling of positivity, or who was uplifting, and even just smiling says so much. I'm sure you can think of things to say that will welcome you, instead of pushing you away from another human being. How you approach a subject, responses you give, and most of al,l putting yourself in the other shoes speaks volumes.
Positive or negative. This choice is up to you. It will be the difference in what comes back to you at a later time. Toss out what you want to come back to you. Even if others give out a negative, don't respond in kind. Do just the opposite. You will be glad you did!
