This daughter isn't usually like that but who knows until I speak up?

The child has access to all the junk food she wants. I'm wondering why my daughter even buys the candy when she's not going to eat it. As far as I know no one else in the household eats it. I have so much to say to her when I get a chance.

It's too bad because the father is skinny as a rail. Why is that fat gene dominant?
