Your best friend always looks on the bright side and is very positive your friend has which personality trait

If a best friend looks on the bright side and is fairly or very positive, they would have positive personality traits. Obviously, there are many personality traits that represent happiness. Do you have any options to this question? If you haven't you could use some of these below :

Nice - A happy person would always be nice to others. They wouldn't ever be jealous of another individual. They would live life helping people on the way as whenever they could help people, they would feel nice and have a thought that they did good.

Good listeners - It is less likely that a happy person would not listen to another. A person that is a good listener knows and is aware of other people's feelings. Those individuals take the time to listen to someone and listen to what they have got to say to them. They would want to resolve problems that could be stopping someone to continue in their everyday life.

These are some examples that I think stand out in happy people. I would note that I am a happy person as well because I enjoy helping others as you can see ;)
