Some semesters are a breeze. Your schedules all line up perfectly, your class load is light as a feather, and you’re able to eat, sleep, and breathe with time leftover. Life seems simple, manageable, and maybe even a little unproductive, but it feels good. Other semesters, on the other hand, are a living hell. It looks good on paper, but when the end of the week rolls around, you’re exhausted, hungry, and struggling to finish your homework and make deadlines. We all know someone with this hectic lifestyle. Whether this is you or your best friend, these are the ten most frequent phrases you’ll hear come out of his or her mouth.

1. "LLet me check my planner.”

I live through my planner. I’m more connected to my planner than I am to my phone, friends, family, and sanity. I write down everything in my planner, from my homework to my potty breaks. If my planner were to get lost/stolen/ruined, I think I would stop existing entirely, and I’m not sure if this fact is causing or decreasing my anxiety.

2. "Sorry, I have class.”

3. "Do you think we could push that back by, say, half an hour?”

I hate to be that person, but if you want to get dinner, it’s probably going to have to be more like a midnight snack.. if I’m done with my project by then.

4. "Sorry, I have to work.”

5. "Does anyone have any caffeine?”

Whether it be through coffee, soda, an energy drink, or Excedrin, I’ll take whatever I can get my hands on. The same goes for food.

6. "Sorry, I have a meeting.”

7. "Can you text me to remind me about that?”

My planner may save my ass and have the majority of my life in it, but it only has so may lines per page.

8. "Sorry I have night class.”

9. "Ah, I can finally check that off of my to-do list!”

Yes, I’m the nerd who makes a list for everything, uses a highlighter to mark off what I’ve accomplished, and gets a high from doing so. Judge me all you want, but I get shit done.

10. "Sorry, I have a sorority thing.”

11. "Sunday? That’s actually the only day that I have any time to relax and enjoy myself in whatever way I please... but sure let’s do something extremely exhausting and time consuming!”

Because even though you’re sleep deprived and starving, you just don’t know how to say no.

And you secretly love it.
