Another mysterious message

Everybody knows about the mysterious "Gleam of triumph" passage in
Goblet of Fire, but there is another strange remark made way back in
book 2, it came right after Harry first found the diary but before he
found out how to use it:

"While Harry was sure he had never heard the name T.M. Riddle before,
it still seemed to mean something to him, almost as though Riddle was
a friend he'd had when he was very small, and had half-forgotten. But
this was absurd. He'd never had friends before Hogwarts, Dudley had
made sure of that."
(Chamber of Secrets, 233-34)

I've read 4 Potter books since then but I still don't know what that
was all about. A friend?!
