Boy: Oh, maybe I'm really becoming a grown up. Do you think?
Mom: Maybe, you never know.


What does "Do you think?" mean?

Does it mean "What do you think? or something else?

Thank you


I'm not sure whether this conversation is correct. To me, I tend to add "So" to the end of the question like the following:

Do you think so?

It means in other terms, do you think I'm really becoming a grown-up?

Thank you so much, Moonrise
