I left Secondary School (even though it was named High School) in 2001. I suppose the ones that are a year or two above me would say the same thing. But I'm glad I wasn't a year or two below. Like zooo mentioned, mobile phones were just leeching their way into schools. Only a few had them. When I finally got one, it never had any credit on it. I just used to carry it around like a saddo.
I'm also glad Facebook wasn't around then. I'd hate to think of never escaping certain people from school. Everyone knowing everything about you. They'd be so many school mates, that blocking or restricting access wouldn't matter, someone else would just download that certain embarrassing photo of you or whatever and share it with everyone.
No, I'm glad I went to school when I did. Innocent times (somewhat).
