The Strange Noise

The strange noise wouldn't stop. I searched everywhere for where the noise was coming from. But I haven't found it yet. No one else seems to hear the noise besides me. I'm starting to think I'm going crazy. Finally Boo said she heard the noise too. But she couldn't find its source either. We searched and searched for days, but nothing. We began to grow accustomed to the noise and we started ignoring it. Then the noise changed. So we couldn't ignore it anymore. Again we looked and looked for the source of the noise. Everyone started laughing at us, because we still couldn't find where the noise was coming from. Finally we just gave up on trying to find the noise. That was when we realized.....it was our shoes making the noise.
