Nothing looks out of place, but... It's still strange that it was in the middle school. Eliza could have forgotten it, or... someone else might've taken it from her and left it there.

[It's seeming more likely that it's the latter, honestly, because wouldn't that be the kind of thing Eliza would write in her diary?]

There wasn't anything in Eliza's diary about her going to the middle school, but does anyone remember if she went by there at all?
