I was going to write about something. I even wrote some preliminary thoughts and a rudimentary draft in my notebook. But I soon discovered that it was going to be really boring, no matter how much I tried to dress it up.
Plus, I thought of something else to write about. And my new thought pushed all of my old thoughts out of my head and they shattered when they hit the floor. So they're gone for good now, those old thoughts.
Now, all I have to do is write something good about the new thing that I thought of.
But not right now, because I thought of the idea quite recently, and I think it needs more time to develop.
