Clumsy

I don't know how many times I've fallen down the stairs in my dorm this year. Tons.

How many steps are there, you ask? There are four.
What are they made of? A very traction-friendly rubber.
What's at the bottom? Carpet.

Yet the four steps outside of the dorm house, which are often coated in ice, give me no trouble.
Obviously there's something wrong with me.
