Definitely not a hoarder

I do the same tbh. I still have notes from when I first started learning music, six years now. I think it helps me keep track of progress and helps with specific memories.
definitely like to know what else was in the bag. I’m wondering what else of the med notes has been presented in the cases already. Like the handover sheet. Just a quick memory recall we have med notes for child m, a handover sheet maybe two? Can’t remember anything else.
would like to know each potential “souvenir“. Im not really attaching any significance to the diary. Think it has three relevant notes. Would be interesting if the majority of the souvenirs corresponded with deaths.
im not quite sure how to read it being under the bed. To me it suggests “out of sight, out of mind” but could be wrong. Could be “keep it for later” as well but It certainly doesn’t sound like the Morrison’s bag was organised in any way.
could it also read that she didn’t associate the notes with a threat? They are certainly not hidden in any way or seem to be a memorial. Does that mean she wasn’t trying to cover her tracks or was it that she deemed the value of the “souvenirs“ to be worth the risk?
