Glenbrook North (also known as GBN), home of the Spartans. Your four years here consisted of many ups, downs, sideways, and diagonals. Here are 25 ways you know you were definitely a Spartan at heart.

1. You freaked out when GBN's spelling mishap was featured on the Tonight Show.

"That's my school! That's my school!"

2. It was a huge victory when you could successfully sneak food out from the cafeteria without the ParaPros catching you in the act.

3. You knew the SAC was "reserved" for juniors and seniors (even though it was for everyone), but once you became an upperclassman, you acted like you owned the area.

"Sorry, no freshmen allowed."

4. Everyone you know looked forward to SpringFest because they were able to show off their new outfits and because of the infamous tacos in a bag, of course.

Straightened hair? Check. 6-inch wedges? Check. Crop top to show off my stomach? Check. Shorts that basically reveal my whole bottom? Check. Taco in a bag? Check.

5. You only looked forward to peer group because of the food.

6. You went all out during Homecoming assemblies and Loyalty Day.

"Fans on both sides! Show your Spartan Pride! We are...GLENBROOK! We are...GLENBROOK!"

7. You always bragged about the fact that the scene where a disguised Ferris picked up Sloane in Ferris Bueller's Day Off was filmed outside of the CPA (and also that the end scene in the Breakfast Club was filmed on the football field).

"Yeah, we're basically famous."

8. When the scent of cinnamon rolls from the Foods I class drifted into the hallway, you raced your way in there hoping you could snag one.

*floats into the room*

9. When the preschoolers walked down the hall, you basically melted into a puddle.

"They're so cute, I can't take it! I just want to mush their little faces!... Aw, look at her cute little dress!"

10. Late arrival days were your savior.

11. You avoided the bathrooms in the B hall like the plague because they smelled horrible and you never knew what would be in there.

"Alright, who didn't flush their period crap?"

12. You dreaded the CrossFit in gym class, when all of the P.E. teachers were staring at you and watching your every move.

13. But you felt extreme pride when you completed the 100 jump ropes, 50 squats, 50 burpees, 50 bicep curls, 50 sit ups, 4 minute standing spin bike, 5 laps, and 25 push ups in the 25 minute time limit.

14. You spent all 4 years wondering who was under the Sparty mascot suit.

14. You got super competitive when it came to football games against Glenbrook South.

15. Friday night blackout football games consisting of hot chocolate and snacks with your friends were the best.

You got to admit, the hot chocolate was pretty damn good.

16. The food court at Costco or La Taquiza became your go to's for open lunch.

17. Your gym uniform still smelled even after you washed it multiple times.

Those lockers in the locker room were pretty mysterious.

18. It made your day when the cafeteria ladies had extra cookies and gave them out for free.

Om nom nom...

18. Having SRT during block 6/7 was the best because you could go to any lunch you wanted and you basically had 2 1/2 hours of free time.

19. The pig fetus dissection in biology your freshman year was probably the saddest day of your entire high school career.

That pungent smell will forever remain in your senses.

20. The junior research paper drained the life out of you.

"So you're saying we have to active read all of our 22-page sources by tomorrow!?"

21. May Day was a HUGE day to show off.

"Roll wave!"

"Hook 'em!"

"On Wisconsin!"

22. You obsessed over the cutest ParaPro.

You know who I'm talking about. Whenever she dressed up as Mrs. Claus, you almost fainted from cuteness.

23. But you despised that other one.

You also know who I'm talking about. You couldn't sit in front of your class until exactly 7 minutes before it started. *eye roll*

24. You bought a new GBN Goes Pink Breast Cancer shirt every year, although they looked almost exactly the same.

You can never have too many of basically the same shirt.

25. You wouldn't change your experience at one of the country's best ranked schools for anything.

Once a Spartan, always a Spartan.
