Opinionated?

Was having a chat with my close friend from poly... the topic drifted to whether we had changed since we first knew each other 12 years ago. She mentioned that I am now less stingy, "harder" thus not so easy to bully as before and opinionated. Yeah I totally agree with the first two observations but I can't really verify the opinionated factor. I mean I was always frank from young. It got me into trouble very often... I was an outcast in Pre-U and that was why I decided to keep my thoughts to myself when I got into Poly. I assume that's why she thought I was not opinionated back then. Opinionated... I'm not sure if I was always opinionated or I become thus after working. Could be from interacting with Ang Mohs frequently?
