In my case it would be “I’m now forgetting everything I’ve just said” and then I’ll convince myself it was yesterday.I used to go out, constantly worried I might have left something on, or forgotten to lock the door.
Then I read something, where a guy suggested that you talk to yourself - out loud - and say, "I am locking the door" or "I am turning the iron off". By verbalising it, you know that you definitely did it. It sounds balmy but really does work!
