This is entirely possible, but my question is, when it was said about
Squibs in the books.  It referred to children of both pure bloods, and
that child having no magical powers.  Now what confuses me is that
how could Petunia be a squib if her parents were muggles?  Wouldn't
she just be an ordinary muggle in that case?
