Lights! I get really pissed off when my mum turns the lights on at 6 o'clock, THERE'S STILL SUNLIGHT WOMAN!! I hate it when lights are on in rooms that no one is using. Also I have this annoying habit, I'm compelled to move the corners of my mouth, it mostly happens when I'm around non-family members so it's probably a nervous thing. I think it may be linked to my ADHD medication because it doesn't happen that much when I forget take take it.
Also I don't like walking, I run or jog everywhere, though I walk when I'm carrying my backpack because running becomes awkward with that thing on.
