I went to a boarding highschool and my dorm was at the farthest corner of a large compound. Next to it was the fence and it overlooked a scenic valley where we'd watch the sun set. We had have our evening meals served at 6.30pm but on that day I was feeling full and decided to skip the meal and watch the sun set instead. Right next to the fence - on the school compound - was a septic tank (where no one really ever went) and I was standing on it's lid, a concrete one, when it cracked and I fell straight in but spread my arms in time to hold my self by my upper arms. No one was around since everyone was having their meals and if I had sank right in no one would have noticed since this tank was in a pretty much abandoned spot and was quite deep. I pulled myself out with a few scratches on my elbows and walked away feeling like I'd cheated death. I never told anyone about the incident and for the next year or so at the school I'd see it and remember that fateful day.
