DH tried to tell me this evening that he had no idea how to press the pager button on the base unit of our landline phone so that it would beep and he could locate it to listen to a message. He does know how. He has done it before.
Suddenly though, with me out collecting DD1 from her friend's house, he isn't able any more. 

Once he had it in his paw, he then tried to claim that he had no idea how to listen to messages on it. Again, something he has done many times before, it isn't a new phone.
I'd bet that he wouldn't do it at work - telling the boss that he hasn't done something he was asked because he suddenly became inexplicably incapable of listening to his voicemail or reading his emails.
He wonders why I looked askance at him.
