Me and sis in garden. Me about 10, sis about 7. Just playing as normal, nothing major happening. Then I started to grab my chest in pain, coughing and gasping for breath. I collapsed onto the floor and passed out. My sis panics trying to rouse me, but I'm out for the count. So she runs inside to get our mum, panicking and crying that I've died. "Come quick!!" etc etc.
Mum sprints into the garden and I'm just casually swinging away on the swing, totally conscious, lucid and breathing. Nothing going on.
Mum tells me off for pulling a prank, that its really cruel to panic another person like that, but I act totally mystified. No idea what my sis is talking about. I've just been on the swing the entire time. Of course I didn't pretend to die!! How stupid, sis is making it all up. Mum believes me and sis is given an early bedtime for attention seeking.
At the time I thought it was hilarious and I was impressed by my own acting skills. I convinced not just one person, but two, with my fine acting!
Now I really do feel fucking awful. It was cruel, my sis fully believed I had some sort of attack and died and was in an awful panic. And then to have my mum punish her and I said nothing... I can't believe I did it. I was actually a really well behaved kid and had done nothing like it before or after. I've no idea why I decided to do it.
I admitted it later in life and apologised to both, but at the time I was remorseless and found myself so funny.
