Because seriously...
Case in point. I just picked DS up from preschool and when we got home he was looking at books. He found something in the book basket and said "I want to keep this." I looked at it and it was the Operator's Manual for my brother's snowmobile. (DB lives with us.)
I said "Oh, you'll have to ask Uncle X when he gets home from work, but I think he needs that."
DS: "No he doesn't."
Me: "Well when he sells his snowmobile he'll need to give it to the new owner."
DS: "He's not going to sell it."
Me: "He is actually. I don't want to argue. Just no, you can't have it. Put it back and find something else."
DS: "No, he's not going to sell it."
And on, and on, and on, and onn.....until he finally gets sent to his room. Then he comes down a few minutes later and tells me he is "ready to be nice." He has a skeleton noisemaker with him that you wave back and forth and the head bounces around and makes the most Godawful clicking noise you ever heard. He begins to play it. Riiiight next to my head.
Finally I said that if he wanted to play with it he could play with it upstairs.
DS: Why?
Me: Because the noise is bothering me right now. Go play with it upstairs and then you can watch your show in a minute.
DS: Why don't you like the noise?
Me: Right now it's just hurting my ears.
DS: But you like it sometimes?
Me: Sometimes it's okay, but not right now.
DS: Why not right now? What if I play it softly?
And on, and on, and on, and onnnnnnn!
ARRRGGGHHH! Am I just incredibly short tempered? It's doing my head in! I try just refusing to engage with him and saying "I'm not going to talk about that anymore" but then he will keep repeating it or tantrum.
Conversations like that happen about every half hour, and I swear every third sentence begins with "But Mommmy...." DS, get ready to go please. "But Mommy...." DS, would you like peas or broccoli? "But Mommy...." DS, the dog doesn't like it when you step on his tail. "But Mommy..."
Does anyone have any advice on dealing with this stage without becoming a madwoman?!
