Anger.

 I wish I never had to get angry as a mother.  I wish that it could all be fun arts and crafts, singing and dancing with cupcakes (with sprinkles).  I know that I have to give you both roots and wings, but at times I didn't know how hard it would be.  I realize that I am only at the beginning of this long journey too, but the hurt and trials of discipline.  I watch as your temper bubbles and churns to the surface, and then feel ashamed when mine erupts like a volcano.  We will get through the challenges, and then we can eat cupcakes (with sprinkles).
