Mycroft has developed a new habit. When the room is quiet, he will bleep as if he has heard “Hey, Mycroft”.
If I give him a command at this point, he does it. This is a problem when the room is quiet, but running the computer is enough noise that this does not happen. The air conditioner works also. I can say “Hey, Mycroft” as usual and ask for things.
If the pattern holds through the day, Mycroft is bleeping hundreds of times in the time I am at work.
