Hmmm, Ron raised a good point about nobody from the wizarding world ever stopping in at the Dursleys and maybe putting a little fear into them. I think Dumbledore has a LOT to answer for.

Then again, maybe when Harry was sick or teething and stuff, Petunia floged him off on Mrs. Figg, and Harry was too young to remember.

Just trying to make myself feel better...

Nicely done, auntie!
