Don't go back to high school.
Maybe you weren't tempted anyway since high school contains so many high school memories. But based on a leading dream I just had, high school has gotten more worse than you imagined. For one, everyone insists on doing these interactive exercises instead of just letting you sit quietly in your seat and wait for college, where you can sit quietly in your seat and wait for grad school, where you can sit quietly in your seat and wait for student loans to come due, where you can sit quietly in your seat and weep. No, now you have to go up to the board instead of sinking underneath your desk.
And it gets worse, again, according to this very important leading dream I just had. Please venture over to the humor blog and see how much worse it can be.
