It’s not the first time that my teenage son Aidan has left for school without the house keys. He forgot them three times this week. Maybe four, I am not sure. He also forgot he had to buy food for Harpo, our cat.
Here’s Harpo just now:

He forgot to tell his mother that I was running late a couple days ago. Highly unusual.
We are his parents and are worried. Yesterday afternoon we went to see a doctor friend that makes the best chips for the head.
With a new type of chip, doors will know Aidan wants them opened, he won’t need keys, won’t have to wait hours on the street until his parents arrive home from work. This morning Aidan was playing football at school when the ball hit him hard in the head.
Looks like the chip moved, rewired or something, and Aidan started talking like a robot. They called his mother and she brought him home. Noticed right away that the front door wouldn’t open for him. Aidan kept on talking in a weird language. She took him to hospital right away.
Aidan has fully recovered after a few hours in the hospital. Looks like he even had a fun time with other kids there that were also talking like robots. That’s barmy isn’t it?
His mother says she was more surprised that several doctors and other people with nice suits visited them non-stop. One of them said someone had cheated with the chips and now Aidan may not open doors at will, but do other things that are difficult to predict.
Nothing to worry, they will be helping out closely with anything Aidan needs.
When I arrived this afternoon, Aidan was waking up from a nap with seems almost no memory of anything happening today. And a headache.
His mother suggested that even with the new chip he would have to carry the keys in his jacket pocket. Or in the backpack if it was warm. Aidan came up with the idea that it was best to carry them always in his hand, the place where they would be ready to be used when needed.
He then right away said it didn’t seem to be a good idea, but that he couldn’t remember why. I think it is the first time he realises on his own that he can’t remember something. Highly unusual.
