What does "You're doing fine" mean?
I watched a movie last night, A Pigeon Sat On A Branch Reflecting On Existence. In the movies, almost every character keep repeating this line: "I'm happy to hear you're doing fine." What is the meaning of that? They are talking in a phone so I don't know who they talked to, but what is "doing fine"?
Solution 1:
Definition of fine:
In good health and feeling well.
Example:
“I’m fine, just fine. And you?"
So, your example is another way of saying:
I'm happy to hear you're doing well.
I'm happy to hear you're doing good.
