So, my 6 y/o little brother (shall we call him David) is trying to go to sleep, has been trying for an hour 45 minutes now, when I decide to go into our room, turn on my laptop, and start browsing reddit.

Now, my little brother absolutely hates darkness, but he stays up for a very long time unless he has darkness. And the closet light has been on all the way the entire time with the door wide open (we have fogged glass doors). I haven't been browsing for a minute when David calls out "Mom, I can't sleep, I've been trying to but OP's computer is too bright"

Earlier today, I had been trying to do my work while he attacked me with his various toys for half an hour until our mom stepped in, so I was already kinda annoyed, but this completely pissed me off. I immediately shut my computer, turned off the closet light, said "Fine. You don't like the light? Have fun in the dark" and closed the door.

Immediately, David starts screaming and crying, causing my mom to chew me out.

AITA?
