I love the free exchange of ideas. I don't even mind being wrong about something - I just learn a bit more - and that, to me, is a good thing.
What I do dislike, is being criticized for stating something positive or being belittled because i don't share the same negative world-view of another.
I'm just glad that, at my advancing age, my mind is still open, that I can feel joy in the smell of the salt air, and marvel at the sounds of so many languages being spoken around me. It's the perfect reason to put on the hearing aids in the morning.
