> Let's agree that we can listen to someone without going overboard, and we can try to de-escalate things without disregarding someone entirely.
Let's never forget that life is way too short to waste time with people not worth our time. They should always be ignored and avoided every time it's possible. This applies even more to people merely looking for attention (among others... TV channels!)
Of course this should be done as politely and respectfully as possible; one should always say "good bye" and smile. Manners.
