The uncertainty of parenting can bring up feelings in us that range from frustration to terror.
The frustration for a parent is that you might be available all the time, but the kid may approach you only about 10% of the time.
In terms of the frustration of my character, I suppose any teenager has probably gone through that, in terms of telling their parents, I want to do one thing, and their parent says no. I think parents sometimes forget that they were children.
Frustrations are going to be there in every profession you're in.
Parenting goes beyond providing foods, shelter, clothing, and other basic necessities. Nurturing a child to travel in the direction of positive enlightenment, is arguably the greatest thing that you could do for a child.
