Not my batchmate but an upperclassman. I used to go to a public highschool where everyone was poor or middle class, absolutely no rich kids. This is in a province in a third world country, so when I say poor, I mean down and out dirt-poor. I made friends with this older guy who I always see on my walk to school. When I ask him where he lived he would always point up to the mountain. I always thought of it as a joke but when he didn't show up for class after a really bad storm, rumors spread that his family's house in the mountains got destroyed. He stopped school after that and I haven't talked to him since.
He finished high school the next year and applied to a prestigious university in the country. He took a finance course but had to stop a few times because of financial issues. He graduated, 6 years later, with honors nonetheless.
Now, he's a regional office manager for a bank and he also owns a small travel agency. The scrawny kid from the mountain became a big time businessman.
