What Normal Adult Keeps Their Yearbooks In Their Bedroom On A Bookshelf? - Tumblr Posts

So I'm reading a fanfiction, and in it there's a serial killer who takes pictures of the deceased out of their yearbook.

In the story they are single parents with one child, so guesstimation their roughly 30 maybe 40 if their children around 15.

Now I'm nearly 26, my yearbooks are stashed in a box under a bunch of other boxes and I really don't care....

Now my question is; is it just me, or is it cuz I was not bullied per se but deeply loved high School...

Like in the story the child and parent get along well, the parents in PTA with the kid, so does that mean they enjoyed high School? or do they just have them because they've got kids so the kids can look at pictures of them in high school?
