Say That Again?

Overheard in the Kitchen:
Matthew: Josh. Jooosh! Come finish emptying the dishwasher.
A few minutes pass, and Josh shows up.
Josh: You know, you could use a different tone of voice when you're asking me to do things.
Matthew: Huh?
Josh: Your voice when you just called me. It was all whine-y and stuff.
Matthew: No it wasn't.
Josh: Yes. You're all "Jooosh!" You were whining. And I really don't feel like doing things for you when you use that voice.
And I'm sitting in the family room listening, thinking, Whoa! I remember saying those same words to that boy (Josh) when he was little. What goes around comes around, I guess.

That little scene was funny enough. But it got better.

Moments after Josh chastised Matthew for using a whine-y voice, he approached Brian with questions about driving his Jeep to school the next morning.
Long story short, Brian said Josh may begin driving the Jeep on his first day to work.
But that answer didn't sit well with our son. And he kept coming back with more questions and slightly different proposals. Each time demanding an answer which "made sense" to him, and each time becoming just a touch more whine-y.
Finally, Brian let out an exasperated sigh and said, "I am becoming less and less motivated to continue this conversation with you." Or something like that. His words were more eloquent. But what I think he meant was, I really don't feel like doing things for you when you use that voice.
