I love the "stash" idea! In that case, I have a stash of notebooks to write future stories in. Thanks to some recent sprees (not sure I've ever spent over $100 at Target before) I have enough to last me... um, yeah, probably forever. Now, notebooks might sound inert in some ways, but I like to get them out and look at them and feel the paper and think about using them, and that makes me happy.
So, okay, $100 on blank notebooks at Target might be a little embarrassing, but I think as long as I don't do it again I should be okay... It would be a lot worse if I bought them and didn't have anywhere to put them in my tiny apartment, which may be the case if I do it again.
