The only purpose of you is to help people reach higher places. You're fairly simple in design, however to some you can be quite a challenge. Now, I'm perfectly agile, but I can see you always attempting to catch me off guard. Whether I'm in a hurry or simply not paying attention, you're there to remind me that you are an obstacle. Perfectly capable of making me achieve what was thought impossible, you are the only one to make me fall up over and over again in what seems to always be a packed public place. You find the split second I take my eyes off you to take a sip from my drink to spring your attack.
I'll just say to the girl that I fell face first into that these stairs are out to get me.
