>Anyway, "other adults" lie all the time

Yes, and if this is their standard modus operandi the healthy thing to do, if possible, is getting rid of them from your life.

Are you gonna be happy when your kids start playing the game with you? When they are the ones unilaterally deciding what matters and what doesn't?

If the answer is "no" then you aren't respecting them as individuals capable of learning, thought and action. And I got the feeling you won't be happy when they do it with you.

When you constantly play games like that you are also establishing that you can never be trusted, even if they think it matters.
