<human>: Give me a shortened version of the text

I'm pretty sure that most of you go through your friend's things when you're over at their place when they aren't in the room.  

For me, I was over at a friend's house and was staying the night in his guest bedroom.  I couldn't go to sleep, so I got up and started snooping through his things.  I opened up a desk drawer and started looking through it.  After emptying it out, I found a stack of raggedy papers.  I started reading them, and found out that they were letters that he and his ex used to write to each other while they were still dating in high school(they dated for over a year.). Some of them were pretty heart-wrenchingly sad, others were boring.
