Whether you have younger siblings or friends still in high school, or you're just supporting a high school activity, you've probably ended up at your old high school at least once since graduating. Here's what probably goes through your head as you walk through your old school.

1. Nostalgia hits you and you really miss the simpler times.

2. But then you remember that you actually had a bad time.

3. And you went through that awkward phase in high school.

4. You remember that boy you used to date.

5. Then you start thinking about all of your old friends. Where are they now?

6. You thank God you no longer have to eat the school lunches.

7. At least you no longer have to deal with group projects where you do all of the work.

8. And you don't have to ask to go to the bathroom anymore.

9. You didn't really learn any important life lessons.

10. However, at least the teachers tried the best they could to teach you something.

11. You wonder how you managed to get to school at 8 a.m. everyday when you can't even make it to a 12 p.m. class now.

12. Despite all of it, you're still happy to have graduated from high school, and you're now a proud alumni.
