Sometimes the things that fascinate one person can frighten another.

When a teenage boy shared his favorite dinosaur YouTube channel with his little sister, he didn’t expect it to lead to sleepless nights and angry parents. Now he’s questioning if it was all his fault.

Read on for the full story!

AITA for showing my sister videos that scared her?

I (14m) have gotten into watching a YouTube channel about dinosaurs.

It’s a cool channel where they play sounds of what they believed dinosaurs really sounded like and post “would you rather” questions about them, like “Would you rather run through the woods with a Tyrannosaurus behind you or swim in a lake with Spinosaurus?”

Soon the videos piqued the interest of prying eyes.

My little sister (9f) saw me watching them in our living room a couple days ago and asked if she could watch them.

So before long, the two began bonding over them.

I let her watch a couple of them and then wanted my phone back, but she still wanted to watch more of the videos, so I pulled them up on her phone for her.

Then she watched a ton of them and seemed to really like them. We talked about them after and she really liked them.

But soon things took a turn for the worst.

This ended up giving her nightmares, and she has been getting in bed with our parents every night ever since.

Yesterday they asked her what was giving her the nightmares, and she told them about the videos about dinosaurs I showed her and how it was really scary.

Now his parents blame him for his sister’s struggles.

Now our parents are really ticked at me and say I never should’ve showed her those videos.

He sees now what went wrong, but he never had bad intentions.

I rewatched some of them today to see why they might have scared her, because at first I didn’t think they were that scary. But after rewatching them, I think I can see how they’d be scary to a little kid.

I never meant to scare her so bad or upset our parents so much.

AITA?

This sounds like an honest mistake any 14 year old could have made.

What did Reddit have to say?

When it comes to the sensibilities of a younger sibling, sometimes it’s best to play it safe.

This commenter would have thought dinosaurs were an appropriate topic for most nine year olds.

Lapses in judgement happen — especially in the teenage years.

He never intended to scare her — he just wanted to find a way to bond over a common interest.

Hindsight may be 20/20, but mistakes happen.
