Ghost slip

They were on a mission that was actually easy, the only problem was that it was raining and the road was very slippery. You met your lieutenant Ghost, you were running towards a place with a roof to avoid getting wet, you were behind him trying to keep up with him when suddenly he simply slipped and fell backwards, you saw everything and the first thing you did was burst out laughing.
"WHAT ARE YOU LAUGHING AT, SOLDIER?" You heard Ghost say as he looked at you furiously.
