Why Do These Things Happen?

The leg of my track suit pants flipped up and tucked itself into the waisteband of my tacksuit pants, just as I was standing on one foot sliding the other foot in the right leg of my track suit pants.

Momentarily, I was stuck. "Ah!" My mind raced.

I was teetering on one leg. I couldn't even wave my arms around to get my balance, as I was hanging onto my track pants. I thought I was going to fall over.

I let go of my track pants, just in time.
