head + desk = ouch

How (in)appropriate is it that it's only three days into NaNo, and I've dropped a book on my laptop and popped off the E key on the keyboard? I managed to get it back on, but it just came off again today, so I'm wondering if I've managed to put it back on permanently this time or if it will keep coming off. And AS I WAS WRITING THAT SENTENCE, it's popped off again. Oi. This is gonna be a long November...
