Is it wrong to count the minutes until my kids go to bed?

I would like to preface this with the fact that I don't feel this way all the time, just most of the time. My mornings are pretty crazy, as I'm sure many of you can relate. I am always telling the kids that it's important that they behave and listen in the mornings as we don't have time for any setbacks. This morning started off to a good start but then it came time to get in the car. We go out to the garage and I am rushing them into the car as it is 35 degrees outside! I see them getting in, I turn to pick up my bag and when I turn back around they are not in the car! I hear a little commotion, a scuffle, and I go around and see that dear daughter and dear son are wrestling and rolling around on the icy, frozen, driveway with no coats on! OMG! WTH? I then realize that dear son has taken dear daughter's backpack and is claiming it as his own, and dear daughter was trying to get it back, sigh..
so I run over trying to pry them apart and not slip as I am doing this. Just then, my next door neighbor is pulling into her driveway with this look on her face that can best be described as confusion/concern combined. So, now I am embarrased as well! I know it was freezing, but I think by the time I got everyone settled and took off that I was sweating. How long until Springtime?
