My macbook has apparently passed on; when I turn it on the screen shows a lifeless gray background with a flashing question mark. I'm not sure what it's asking but tomorrow I will trek up to the Apple store to get a diagnosis. I will probably need to buy a new one as the symptoms have been getting ominouser and ominouser (like curiouser and curiouser) for some time now.
In the meantime I am slowly and labouriously typing out this message on my Kindle Fire. Please be patient with me while I remedy the situation. I will be back!
