This morning, I woke up and went to my work place called bobby's builders and my manager said "we have a broken pipe that needs fixing underground" so I spent my night drilling the concrete and but when I fell I dropped my keys it came down the drain pipe so I went to the underground floor. As soon as I got to the bottom I saw the rusty pipe leaking with dirty water but I didn't see my keys at all I was searching everywhere but it was useless I searched up down left right but it wasn't there.
