A perfect world for me would be that everyone is happy, and that there´s just peace and love in the world. No sickness, and no tragedies. Everyone just lives a happy life with many good friends, and a big family who cares. And that the would would just consist of goodness, and no people that does harm and and awful things.
If I could´ve decided where I would live I would pick a place with beautiful beaches, surrounded by nice people and hot temperature, something like Hawaii or Thailand. The sun makes me a happier person :)
