The world is full of nice people. If you can't find one, be one, meaning irrespective of your circumstances, be nice to people even when people around you are not nice.
Sometimes making yourself the spotlight among others makes you look unique and different. If people seem to act wayward, that does not mean you should act the same way. There are some situations we find ourselves in, and what we expect seem to be different from our expectation. In reality, people have different attitudes, views, and thoughts. There are times we expect friends, family members, and even strangers to be nice to us, but they act differently. They do not show the feeling of humanity, and we feel less important. Whichever situation you may find yourself always be nice to people around you. When people see the difference in you, they will want to associate with you. They will look up to you as a role model. Now, imagine you are visiting a place for the first time, and you approach some people to make more findings or to clear your curiosity; they treat you badly. Obviously, you will feel rejected, but that does not mean everyone is like that.
In life, learn to make a difference. Always consider people and treat them nicely. When you do not meet a nice person, you should be the nice one. Remember that the way you address people speaks a lot about your personality, and that is what matters the most.
