The friend responds Oh, how did that happen?.
Kai responds My character had a grenade and I had to make a quick choice on how to react, I decided to hold onto it and my character died so my team lost the round..
The friend responds That sounds like a dumb decision..
Kai responds It was really stupid and my team lost the competition as a result..
The friend responds I'm sorry that happened to you..
