staring into space
when you stare into space you are generally looking in the direction furthest away. its when you have been left to your own thoughts, and with no-one to talk to but yourself, and the pointlessness of losing your eyes cause it takes too much effort you just stare at no place in particular. If you're staring in to space, don't stare at any else, especially not your secret crush, it's weird mate and frowned upon.
