When I learned to walk, my parents too put a barrier, specifically a gate, in front of the stairs. It was an especially dangerous stairway, as the steps had no back, so I was liable to simply fall through them. But, being a crafty little bastard, I soon figured out how to unlatch this horrific impedance. So they started tightening it with a wrench so that I wouldn't be able to undo it, and they put the wrench on top of the TV, where I couldn't reach it.
So one day, while my mother was reading the newspaper in the living room, I went sneakily about in front of her while she pretended not to notice me. I made a sort of stairway out of the drawers of the dresser the TV stood on, climbed up, and snatched the wrench. I went running over to the gate, and looked at the wrench. I didn't really know what to do with it, so I simply waved it at the gate like a magic wand, and was mysteriously able to unlatch it and ascend with glee. My mother ran over to the stairs and asked,
"Where are you going?"
To which I responded,
"To London, to visit the Queen!"
