So I was standing at a corner, waiting for the lights to change, and I was daydreaming and staring into space. I thought of something someone said to me that had been funny and I started grinning and kinda chuckling, and then I came back to consciousness and realised I had been staring at a guy in a wheelchair, laughing, and he was staring back at me. I got the hell outta there - I don't wanna see the rage of a wheely.
