Scewed Grading Scale

There are days when if I was grading myself in parenting I feel like a C, somedays a B.  I wonder if other parents feel this way.  Mainly I wonder if my neighbors consider themselves an A.  I wonder if they just don't realize being parents mean being responsible for your children.  Maybe they don't consider knowing where thier kids are a big deal so in essence they are an A.  I just know if there were five minutes of the day that I didn't know where my kids were I would give myself a F-.
