I really don't know.After finishing my school I haven't heard about my old classmates a lot.
I forget them some how,but in order to their characters, I think they just wanted to make a good family.
If I were you, I'd write something like this:
I don't really know. I haven't heard much from my classmates since I finished / graduated high school. I don't even remember much about them. I don't think anyone from my school has become famous. From what I can remember, they all wanted to settle down and start a family.
