1. Not tipping

Seriously? If you don't have enough money to tip, you don't have enough money to go out. Waiters and waitresses don't even get minimum wage. They're living off of your tips, so next time just tip them. Here is a tip of advice for you for next time: most girls would rather be impressed by a homemade meal, not by someone who doesn't tip.

2. People who spell simple names wrong (and people who have weirdly spelled names)

Give someone the easiest name to spell and they will use every letter in the alphabet other than the ones in your name. My biggest grudge has to be for the people that name their kids with every single letter in the alphabet. Why are you making this hard for us?

3. Chewing with your mouth open

Come on. This one is common sense, do I really have to tell you this is a pet peeve. No one wants to listen to you chomping like a cow, even with your lips cracked open in the slightest way, we can hear it.

4. Not using your turn signal

Come on, guys! How can I possibly know that you're turning? All I know is that your car is slowing down in the middle of the lane. At the worst, your car could be breaking down right in front of me, but all you're trying to do is turn.

5. Easy grammar errors

Learn it, people! Just because we know what you're saying, doesn't mean we want to see the mistake. For those of you that may not know: You're = you are. Your = possessive adjective.

6. People who walk slow right in front of you

Walk slow on your own time, but make sure to stay out of my way. Don't cut me off on the street or in the hallway only to go half my speed or I will step on your shoe.

7. Flies

Why do they exist? This is a serious question. No one likes to have them buzzing around your food, and if you're having a picnic outside, it's near impossible to keep them away.

8. White board erasers that never properly erase the ink

I had no pet peeve growing up that wasn't bigger than this one. I didn't race over to grab the best white board only to figure out they all look like this. They're not that hard to clean, yet they look like they've been submerged in filth for days.

9. Interrupting

I'm sorry, was my talking too boring? Did you have something more important to say? Do you just not have any manners? I'm gonna have to guess it's the latter.

10. Leaving laundry in the washer for too long

If I go to do my laundry only to realize that it still has your clothes in it, this is the face I'm going to give you. Not only does it make your clothes pretty gross leaving it in the dryer, but you're wasting my time having to wait for you to take it out.

11. The section of hair in the back of people's heads that never get properly straightened

I do understand the struggles. I'm pretty sure I walked around middle school for three years with a tiny wavy chunk of hair at the top of my hair in the back, but come on! How much more work do you have to go through to make sure you don't forget just one piece.

12. People who talk in libraries

Do you not realize the point of a library? This is not social hour. This is the time for me to stress silently over the work I have to do, not listen to a group of people chatting loudly a few tables over.

13. Sub-tweeting

I'm not even going to insert a picture here because by doing that, I would be indirectly talking about somebody. If it's a big enough problem to post about it on social media, then you should have enough decency to talk to the person the problem is with.

14. Making plans in front of someone you are not going to invite

There's nothing like having the fact that you weren't invited to something flaunted right in front of you. You might as well tell the whole world that I am not invited, that's how it feels.

15. Redundant hashtags

What are you going to get out of that many hashtags? How many of those are relevant to the photo? No one wants to read through 31 hashtags. At that point, you are just overusing it and the whole community of social media would like you to stop.

16. People who walk into stores right before closing

Stores have opening and closing hours, and their employees really do like to go home on time.

17. People who say "I could care less"

I'm just going to assume you stopped caring enough long ago to the point where you just don't use phrases correctly. It's honestly not that hard for you to learn.
