In high school, you didn't have a choice, you were stuck going to school whether you liked it or not. Even if you hated the school you attended, there was nothing you could do about it. Most high school kids probably can't convince their parents to move because they don't like their school. And even less possible to get them to fork over some money for a private school, which isn't much different than high school, anyway. They just have more money.
College is full of choices.
If you hate the college you attend, you can drop out and still be respected. Or, you could just transfer to a different college. Generally, most people in college are also intelligent and mature, so you don't have all the losers that you're stuck with in high school. That's why I'm here. Homecoming isn't needed, it really seems like a high school event.
