The only reason why I made this project, was because I hate seeing people sad. Right now, we all may not be in the best place. And that's okay. We might miss people that we don't have control of whether we see them or not. We might start hating people. We might start feeling like the world is crashing down, and you can't do anything about it. Don't be mistaken, you have so much potential. You can change someone's mood by smiling at them. Incredible, right?
