Tragedy of An Auto-Flush Sensor

I was built to serve the forgetful masses in the toilets. But the moment I was installed, an omnimous feeling overcame me.

When the first person my buddy served came in, he opened up the seat cover. Then, darkness fell. And then on, I could only hear sounds...

Then, I felt my button pressed. I let my water out into my buddy. It was done, but it wasn't the same and it never will be. I realised I could never fully satisfy the people I was created to serve. I felt betrayed by the contractors who installed me. I have lost hope in humanity.
