The Shmunkin has a thing about wearing mittens. I'm not sure what it is, but whenever we go somewhere, as soon as we get into the car, she asks if she can take them off. I suppose it could have something to do with Big Girl School. At the end of each day, there is a basket of snacks -- crackers and the like -- for kids to take on the ride home, and it's hard to eat them with mittens on.
Normally, when she asks to take them off, I tell her to go ahead, but to make sure she puts them back on when we have to get out again. And, normally, I have to stand in the cold and put them on for her, because she either forgot or didn't want to do it herself.
So we had dinner with a few extended family members the other day at a restaurant about a half-hour from our house. When we left, as soon as we were in the car, she asked to take her mittens off. It was still cold, and I didn't want her hands to freeze, so I said, "No." This resulted in the beginning of what could have resulted in a pretty major issue -- she was on the verge already -- so I quickly caved, but told her she must put them back on herself when we got home.
The entire drive home, she was quiet, and I figured she was asleep. As we neared the house, I told her to put her mittens back on. She said, very firmly, "No."
I said, "[Shmunkin], put your mittens on."
Even more firmly, she said, "No!."
Now I decided to use my Daddy Voice. I think I have a pretty good Daddy Voice. I have one of those very low, strong announcer-voices to start with. Back when I worked in radio, people who met me in person for the first time were very surprised to find out how much younger I was than I sounded. (Of course, that is no longer the case. Now, apparently, I sound as old as I am.) Anyway, I can easily make my voice even lower and firmer when needed, which, combined with slowing the pace, provides the firm, authoritative, serious-sounding Daddy Voice. So I used it:
"[Shmunkin's full first, middle and last name], Put. Your. Mittens. On. Now."
To which she replied, in a very (for her) low, slow and serious-sounding voice, as if mocking me, "No."
So I pulled over to the side of the road, stopped the car, and turned around, and was greeted with a look very similar to this:

If you've even met The Shmunkin, you will instantly recognize that as the look she gets on her face when she believes she has just pulled off the cleverest, most hilarious gag in the history of time (picture taken at a different time, but it's the same look). Her hands were up in front of her and, on them, were the mittens. She had put them back on, and somehow managed to stay quiet about it until the time was right.
I'd like to say she gets her sense of humor from me, but I think she may be funnier. Of course, being three, she also has attempted the same joke about two dozen times since. And that is definitely like me.
