How are you going to be?

Nokomis has been behaving very well the last two days.  She has not been been bothered by her siblings nor has she bothered them.  HOWEVER, last night she was very explosive and could not settle down for bedtime.  Today, when she was playing by herself I told her how well she had been acting just like yesterday.  I than asked her if she thinks she will be this way tonight as well.  She said, "I don't know".  I said you mean you may act like last night.  She said, "I could".  I than asked if that's how she wanted to act tonight.  She told me that's not how she wanted to act.   Let's hope all will be well tonight!
