I'm not doing Bingo this month, so I didn't read the layout prompt you're asking about. I'm sorry if my ideas make no sense for the prompt!
I've scrapped a few pictures of my DD looking through our albums and journaled about why I scrap or about how much I love that our stories are important to her, too. Maybe a photo like that where you can see the layout that someone is looking at?
I scrap vacations in separate photobooks then just put a couple of pages of highlights in our main album. If you happen to do anything similar (doesn't have to be vacations; anything scrapped in its own album or photobook would do) you could do a page with some of the pages from the separate album.
I think your sons graduated HS this year, right? Maybe a look back at first day of school layouts over a period of time (K-12, high school only, a few random years, etc.)
Good luck finding an idea that speaks to you!
