Gum

I was at the bus shelter with the missing roof, waiting, and I had just sat in gum. I knew that I had sat in gum because a minute before I had looked at the foul grey blob of it clinging to the seat and thought, make sure you don't sit there. But the world span the thought out of me as quickly as it had come, and I sat. The bus came, late, and I waved the driver on. The gum would only become a problem when I stood up, so I stayed, stuck in place, until I could think my way out of it ever having happened.
