Hello, Like, I am SO Dumb!

So today I went to grill some steaks outside with my daughter for lunch. For a treat I got myself a glass of red wine and got my daughter a wineglass full of apple juice. She was delighted. I put the steaks on the grill and I went to take a sip of my wine. She went to take a sip of her apple juice and smiled. I realized that I should make her do "cheers" with me. The boys love that. I said to her:
"You know what we should do?" And I held up my wineglass.

She looked at me like I was sort of stupid. "I know what you're going to say, Mom, cheers."

"Yeah, don't you want to?" I ask, disappointed.

Mind you, my daughter is five.

"Umm, not really," she says like I should know already and she is really embarrassed.

"Why not? Aren't we the girl's club?" I ask her.

"Yes, we ARE the girl's club! But saying cheers is just---DUMB!" She says "dumb" like a valley girl saying "Hello! Get a grip!"

"What?!" I say, totally shocked.

She just slowly closes her eyes in a sweet way, looks down, smiles, and shakes her little blonde head. "Oh, Mom."

I think she is more mature than me.
