We all want to express what we think, no barriers, no judgments or anything. But that's not the world we live in. "Dance like no one's watching" is what they say, but why should we worry what other people think? Here are 15 reasons why we need to keep quiet.

1. Waste of time

You're mad at someone because you're in an ongoing argument with them. However, you're also dead-set that you're right, that you can't express the something enough to the same stupid guy. Or you're positive there's nothing that can change your mind.

2. Too nervous to

Perhaps you know you're wrong but you don't want to be told so and have to defend your wrong point of view (because you're so dang stubborn).

3. To prove a point

When you're angry with someone, sometimes silence is all they deserve.

4. It's awkward

Burned bridges with anyone? Friends, family, or even coworkers might be repairable but wanna talk to the ex? To find out just what is wrong with you that they don't like you for... To share with them inside jokes that only they would think is funny? You simply can't because society states that it is unwelcome to speak with people that either broke your heart or were broken hearted because of you. The heart says that it is frowned upon to be in the vicinity of the ex, that tears, magically appearing fists, and inability to control speech may be present in confronting them.

5. It's polite

When someone's asleep, or someone is grieving, it just is not the time to bring up heartfelt arguments that have been burning inside for so long.

6. Powerlessness

Lex Luther: "The bittersweet pain among men is having knowledge without power because... that is paradoxical."

7. Complacency

When one has a great mind but no intentions to disrupt the status quo. Even if their idea is influential they lack the energy to speak up and embrace the change.

8. No entrepreneurial spirit

Risk. The centerpiece of entrepreneurship. The reason some of us avoid speaking up is our lack of risks being taken. When that hot guy or girl walks into the Wawa you're in, its the fear of problems that keeps you from walking up and sweet talking your way to a first date.

9. Inferiority complex

Trying to talk back to mom or dad, it might be hard because you know they have coercive power over you. You can be grounded and scolded even for telling the truth, to have witnessed something they don't believe, for not knowing anything, not having anything to do with something, to honest-to-god have forgotten something. If you backtalk mom or dad, you could be looking at another hour or two of scolding.

10. Keeping a secret

Being a good friend, or a good brother, or even parent, means keeping a secret sometimes when a topic is brought up. Personally, I feel this calls for a sufficient amount of acting experience to be able to pretend like they don't know the truth. Even if they think their friends would love to hear this secret, you gotta lie or walk away.

11. To reach an anticipated result

If you don't say anything, sometimes you're more likely to get something. Whether it's prom and you know you're involved in a disciplinary worthy activity. You know your mom is looking for her old bottle of wine, you know your brother will get blamed, yet you know you took it for a party last quarter. You know you'll get the team captain job if someone else gets in trouble for egging coach's car.

12. "You jinxed it!!"

Google Definition: "Bring bad luck on; cast an evil spell on"

We can put bad luck on ourselves simply by speaking of what we want, especially when what we want is high stakes and at volatile probabilities of achievement.

13. Keeping the peace

Y'all having a civilized conversation in a group of 4 or 5. You have the opportunity to say something yet you know if you do, this one guy would get "triggered" and begin a long strung out argument.

14. Simply too busy

Sometimes you're too invested in a book, video, or self-loathing. Either way, ya want to be on your own, no problem with that.

15. Lack of expertise

We all know when we shouldn't be talking on a certain topic; we know what we know and don't know. Consequently, if we know what we don't know, we know what not to argue about.
