There are so many questions I have always wanted to know or the "why is this this way" sort of thing. So. here are some!

1. Why do people smile then they are about to cry?

2. How do people say they know how the other person is feeling through their eyes?

3. Why do people bring up situations to other people that they know are sensitive to them?

4. How is it called peer pressure when the person says yes?

5. Why do people say their your best friend when they get mad at you so easily?

6. How come parents are so naive when they were worse?

7. Why do people say they have your back when they don't even have theirs?

8. How can people hide their emotions?

9. Why are teens so controlled?

10. How can people say they have more than one best friend when best means the best?
