When the curtains have a gap inbetween them with a tiny bit of light coming through. I have to get out of bed and make sure they're fully closed. When my OH turns the volume on the TV up using the sky remote, and not the actual TV remote. Because I like both volume metres to show the volume in the middle of the bar, and dont like one being high and the other being low. When people dilly-dally before doing something really important or nerve-wracking. I get nervous about such things and want them done as soon as possible and out of the way - it winds me up when people start faffing around, or having a cup of tea first because it makes me nervous on their behalf! (Hard to explain this without giving too much away about school issue) The cutlery not being put back in its seperate compartments in the cutlery drawer.
