May have just lost my the last chance to hear her voice. Her Dictaphone was flashing "battery low" so I replaced the batteries - and have apparently wiped all the previous recordings in the process. I wasn't ready to listen to them and picked up the Dictaphone by chance during my frantic cleaning today. If the low battery had wiped out messages it would have been bad enough. But it looks as though my usual mechanical stupidity has done it. I wasn't ready to listen to them and now I never will. I don't if there was even anything on there, of course; but now I'll never know.
I'm so sick of being a fucking moron.
