Question for Those Who Love Harry Potter

Disclaimer: I don’t make it too much of a secret that I am not a huge fan of the series. I don’t hate it. I just don’t love it. And I’ve only read the first three books (almost 20 years ago!)

Which leads me to my question:

It’s about Harry’s uncle and aunt. (You can throw in the cousin, too, if you want.)

How much page-time do they actually get in the books?

From my memories of the first books is that they are pretty much just mentioned. We may even briefly meet them. We basically learn how awful they are (you know, Harry sleep under the stairs). But after that, they don’t actually physically appear in the books.

Is this correct? Do they get some serious page-time, and I’m just not remembering this? Like chapters? Huge dialogue sections? Perhaps this happens in Book 4 or beyond?

Please let me know in the comments! Thanks!
