I went outside this morning, and walked toward my trike. The trike is permanently parked outside, because I definitely cannot keep it inside. There is literally no space. It's not a matter of inconvenience or apathy - I live in a half-finished attic, and there are like... a thousand steps and doors between the street and my room. I already have two bicycles stashed in a common hallway up a flight of stairs. The trike is about as practical to keep inside as a horse farm would be.
In the many months the trike has lived outside, nobody has bothered to slash a tire. Until today.
