How did you scar someone for life?

My sister used to sleep with this giant stuffed dog that was probably four feet long.

She'd put it on the right side of the bed and cover the dog with a blanket so it looked like a body pillow.

Anyways, in fifth grade, I thought it would be funny to play a prank on my little sister.

I took out the dog and I climbed into her bed and covered myself with the blanket

where the stuffed dog usually was while she went to talk to my mum. My sister comes back and

climbs into bed to sleep while I'm laying in the bed with her without her knowing. It's dark in

the room. I lay there in silence for maybe about three minutes when I finally go, hey. She literally screamed

at the top of her lungs and ran out of her room so fast that she knocked over everything

along the way to my mum's room. It was probably one of the funniest moments of my life. However,

I did scar my sister so badly that to this day, and she's 20 now, before she climbs into bed, she

always removes the blanket to check if anything is underneath. Needless to say, she almost

had a panic attack watching the grudge. You guys know the scene I'm talking about. So, what are the

rest of you done that scarred someone for life? I just learned this month that one of my three sisters is afraid of vampires.

I had accidentally tripped the breakers in the house one night while my parents were out,

and I was watching them. I was 12 and my sisters all gathered in the back room, the only one

that still had power. I saw this as an opportunity and targeted the youngest who was six. I told her that

I'd cut off the power intentionally and that I was a vampire. I told her that I intended to eat

her and as I did this, I suddenly leaned in close and bared my teeth. All three of my sisters screamed,

and the elder two fled the room, each out of opposite doors.

The youngest, abandoned, instantly burst into tears and grabbed the nearest weapon, a serious

pair of scissors off a side table. As she lunged, screaming at my chest, I saw the fear
