Basic Trope: Writing on the walls shows obsession.
- Straight: Alice is obsessed with Bob and has covered every wall in her room with notes about him.
- Exaggerated: Alice is obsessed with Bob and has covered every wall in her house with notes about him.
- Downplayed: Alice is obsessed and one wall — her "thinking wall" — is covered with notes.
- Justified: Alice has graphomania and doesn't want to use paper to document her obsession.
- Inverted:
- Alice writes on the walls, but she's perfectly sane with no obsession.
- Alternatively, everyone else writes on the walls regularly, but Alice doesn't because she doesn't want them to see her obsessive thoughts about Bob.
- Subverted: Alice is obsessed with Bob and writes notes about him all over the walls...but it turns out that the "Alice" who wrote the notes all over the walls was a shapeshifter.
- Double Subverted: When the real Alice escapes and finds out, she breathes a sigh of relief...now she can blame the notes she wants to write on the walls about Bob on the shapeshifter.
- Zigzagged: ???
- Parodied: A spot on the wall has fading text... and then a few lines later, Alice apologizes for her pen running out of ink.
- Averted: No one writes on the walls.
- Enforced: ???
- Lampshaded:Charlie: Those notes about Bob were all over the walls. She's more than a tad fixated.
- Invoked: Dr. Evilstein uses a potion on Alice that turns her focuses into obsessions and gives her graphomania.
- Exploited: Bob uses Alice's wall of notes to keep track of her knowledge and plans.
- Defied: Alice is about to start writing when she decides it would be better to keep everything in her head.
- Discussed: ???
- Conversed: "People in movies always have these rooms full of notes about stuff they're fixated on."
- Implied: Charlie goes into the room to check it out.Bob: I've got a Stalker with a Crush, haven't I?Charlie: Take a look at these walls and see for yourself.
- Played for Laughs: Alice is obsessed with Bob and has covered her walls with notes about him, but many of those notes are crossed out from misspellings or trail off due to the pen running dry, and a third of the wall is covered with Alice cursing the pen or just writing random things that come into her mind.
