The context of the following conversation is Kai was holding the grenade and didnt know what to do. he could throw it out the window or save it for himself if they came in. Being a first degree Army sergeant, he eventually he made his choice and blew himself to kingdom come.:
Kai says That video game I was playing last night was so realistic!.
The friend responds Really, what happened?.
Kai responds I blew myself up with a grenade. I was holding it and had to decide whether to throw it out the window or take myself out if the enemy team came in. Since I'm the sergeant I decided to take one for the team..
The friend responds Wow you're really courageous!.
Kai responds I am not sure if it was the correct decision, I couldn’t respawn until the next round of the game..
The friend responds Well at least you can try again another time..
