You’re allowed to change your mind.
An opinion can be a starting point, rather than a permanent address.
A question worth keeping close: what would make me think differently? It leaves room for a conversation to become something other than a contest.
Changing your mind can mean you have noticed a detail you missed, heard an experience unlike your own, or found a better question. You can take that seriously without turning the moment into a dramatic reinvention.
The next time you feel certain, get curious about the strongest version of another perspective. You may keep your opinion. You may adjust it. Either way, the world gets a little less flat.
