1. Loud chewing

When is it not annoying when someone chews extremely loudly? It sucks when you can hear their food smacking and it all makes uncomfortable noises that you can't bear... Worst part? The person usually isn't even aware that they're being so loud.

2. Clicking

It's so distracting when you're in class trying to concentrate, take a test, or complete an assignment, and someone is nonstop clicking a pen in your ear. Any sort of clicking is distracting, but pen-clicking definitely tops the list.

3. Blocking the sidewalk

It's the worst when you're stuck behind a cluster of people because they're taking up the whole sidewalk. There is almost nothing you can do in this situation besides walk into the street and risk your life or deal with it and try not to scream.

4. Holding doors

When you hold the door for someone and they don't say anything, it hurts a small part of you—specially if you went out of your way to hold the door or if they were a distance behind you. The least you could do is nod, or give some sort of acknowledgment, right?

5. Talking over you

There is nothing more awful than someone talking over you mid-sentence. It's as if what you were saying had no importance or value whatsoever.

6. When someone else bumps into you, but they act like it was you

This is especially true on the subway or bus when it's crowded. Do you really want to be that close to a stranger? No. If you bump into me, sorry, but it's not my fault.

7. Those people that don't have time to answer your text, but have time to post on social media

There's definitely a difference between forgetting or not seeing the message once or twice, and completely flat-out ignoring a person. Can't you just text back?

8. Being quiet in theaters

It sucks when people won't keep their mouth shut when you're trying to watch a movie. You paid money to sit in the theater and watch this brand new movie, but those other people don't have the decency to stay quiet for a couple of hours and enjoy their money's worth?

9.Texting loudly

On public transportation, it sucks when people text and their volume is all the way up and they're texting about a thousand people at once. It's hard to deal with constant clicking, beeping, chirping, and other noises.

10. Shoulder sleeping

What do you do when someone on the bus falls asleep on your shoulder? Do you wake them up? Let them sleep? Push them over? What is there to do in this situation? Of course, it depends upon what kind of person you are, but nonetheless, the decision is a difficult one.
