Thank you for your kind replies.
One thing that I didn't comment before is this quote
I don't know how you define the maturity, but Yuna achieved in her respective field more, than, I guess, most of the people on this board and she certainly can take the responsibility for her actions and even for other people. She may be impulsive, she may be stubborn, but I don't think she is immature.
When I read it, I cannot help but laugh. "She may be impulsive, she may be stubborn", she may be ego-centric, she may be a *****,..... "but I don't think she is immature." Get my point? Can you explain it in a more logically friendly way? Thanks.
