<human>: Can you provide a brief overview of the text?

This was when I was in high school around 1993.  We were in a friends basement playing pool and having a few beers.  My friend's brother lived in the basement but wasnt home and had left his 38 snub nose revolver sitting on the mantle.  My friend picked up the gun and jokingly said "Anyone wanna play Russian Roulette?"  I jokingly said "yes".  Now I had no intention of really playing, I was trying to shock them.  First I snuck a look at the gun to see where the bullet was, it was the one before the chamber, perfect I thought, this thing is definitely not going to fire.  So I put the gun to my head and pulled the trigger, BOOM!!!!!!  I hit the ground, immediately and felt what I was sure was blood running down my face (it was just panic sweat).  I thought  this was one of the dumbest ways to die, really it was like those 10 seconds between hitting the ground and opening my eyes lasted a year.  I slowly realized I was alive and felt my head over and over, I just couldnt believe I was alive.  I guess at the last minute I chickened out (Thank the Lord) and pointed the gun up instead of at my head.  It blew a whole in the basement ceiling, upstairs living room floor and lodged in the ceiling upstairs.  I still to this day have a loud ringing in my ear that will never go away (nerve damage).  I obviously dont like guns now.  Turns out the bullet next the chamber is the one that fires, really wish I had thought about the word revolver before I made that stupid decision.  I still have never told my parents what really happened.  I dont want them to know they raised a moron.
<bot>: didnt know how revolvers worked, played Russian Roulette as a joke, almost blew my head off, have permanent hearing damage.  Guns are dangerous kids, especially if you've never been trained with one.
