Questions bugging my mind

Here are some questions that are bugging my mind these days:

1. Why are there people who claim that you might be insecure but they are the ones who really act insecure?

2. Why are there people who bug or nag at you always even if you are not doing anything?

3. Why are there people who only think about themselves in terms of they only want you to listen to they have to say but you can't talk back or explain your side of the story because they won't accept it.

4. Why are there people who pretend to have money but in reality, they don't have extra money?

5. Why are there people who don't treasure simple things but instead pout on more extravagant things?

6. Why are there people who don't appreciate simple persons around them but instead they try to pressure those simple people to act like them?

7. Why are there people who don't respect others for whom they truly are?

8. Why are there people who don't know the real day to day reality of life?

9. Why are there people who are lazy and earn free money?

10. Lastly, why are there people who live on finding faults of others who don't do anything to them?
