Say I have a book open, and the page on the left is A and the page on the right is B. There is a picture of me on page B. I'm pointing out to my friend over text that there is a picture of her on page A, but I'm highlighting the fact that we're both on the same page! But not literally on the same page. Just, you can see both of us when you are turned to this page. I can't say "you're on the previous page" because it might mean you have to flip back a page to see her picture, which isn't as special. I can't say "We're next to each other!" because that's not very correct, there are other people on the page that I am on.
How do I word this? Is there a word for this? "We're on the same ____ of the book!"
