I was coming to the computer to do something "really important"... and then I forgot what it was so I'm feeling a little Pooh-ish...

"I don't see much sense in that," said Rabbit.
"No," said Pooh humbly, "there isn't. But there was going to be when I began it. It's just that something happened to it along the way."

I feel this way a little too often it seems... sigh.
