So, I've gone back to an old habit of marking down when characters say "we should get together" for scene possibilities (or when another player says it) but I'm not 100% perfect at it.
If you're interested, think you remember one I don't (please comment!), just want to point and laugh at me because I basically keep a social calendar for my characters, you can find the current list here: http://matsujo9.insanejournal.com/296312.html
