Ghost slip

They were on a mission that, truth be told, was easy; the only problem was that it was raining and the path was very slippery. You were with your lieutenant, Ghost; you were both running toward a sheltered area to avoid getting soaked. You were behind him, trying to keep up with his pace, when suddenly he simply slipped and fell backward. You saw everything, and the first thing you did was let out a laugh.

"WHAT ARE YOU LAUGHING AT, SOLDIER?" you heard Ghost say while he looked at you furiously.
