At first I thought I would just change everyone else and make them the way I wanted to but then at the same time if you could do that to everyone I don't think it would be that interesting to live any more.
I don't think I would like to change the skin color of people. I find most anyone can be beautiful regardless of their skin colors but I would like to see that people just didn't care about it :).
And I would make it so that people wouldn't judge each other just based on what they do (as long as they don't do anything to hurt someone) just because they don't do what they think is right. In short they would be more accepting I guess Emoji.
That's a bit weird but I do understand why you wouldn't want to stop doing things you like. I don't think I really have any allergies. Except for rosemary. But maybe I do, I've never tried it :).
