Sometimes I write just for the sake of writing.
Usually, I'm bored.
And if I remove it later, well, it's not like I made a mess or anything.
It's also times like these that I think maybe I should get one of those hardbound dead-tree journals and use that. That wears off in about thirty seconds.
Keeping a journal also implies that you'll want to go back to it later and find how brilliant you were back then? No illusions; I'm not that smart. Ha!
