Not the first time.
Doubt it will be the last.
Was stood in the kitchen (small galley kitchen) with DD. I had the dishwasher door fully open which takes up almost a 3rd of the floor in area so I asked her to go out. She sort of huffed and stormed out teen style, I had turned to the side to put something away and as she left the room I saw, what I thought was DS run in past her and behind me.
It all happened in a second. So I turned round and he wasn't there, I stwp around the dishwasher door and see DD closed the door behind her.
I realise DS couldn't have ran in behind me anyway because the dishwasher was open. So the person effectively ran through the metal door complete with extended rack and plates.
Then I realised further that the boy was smaller than DS is.
I've seen him before.
Obviously not everyone will believe me. Some will say its trick of the light or a hallucination. Or that I'm plain making it up.
But like I said. It happens often.
