Every night before I go to bed, I get half an hour to go on my laptop, go on Facebook, EMC and the other things I do. I usually spend this time in the dark lying in my bed with my laptop to my side.Two minutes ago, my mum made me turn on my light. She said it's bad for my eyesight to look at a screen in the dark. I told her I have f.lux, so it's okay, she didn't listen.I went to turn off the light, she heard, we had an argument.After saying that yes, I'd turn on the light again, I very quietly turned it off.It may seem simple, but I like having things in a certain order, and that includes the freedom to have whatever damned light level I want in my room when taking my half hour on the laptop. She's going to come upstairs in half an hour to take my laptop and rage at me for having my light off, and I'm prepared for that.If you can't even counter my argument with a rebuttal, I will have my damned way whether you like it or not, Mum.Also, this is my 2,000th post. Well spent, I say.Thanks for being there to listen to my random frustration, EMC.
