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

So this happened a couple of months ago , but it was a pretty big fuck up so I will post it anyways. 
Me and a female friend of mine ( both in our 20's ) were goofing around between classes in front of our university and while I was sitting on a bench she jumps on my back and me , being the strong fucker I thought I was , tried to stand up and carry her . Of course I lost balance , tumbled forward and she face-planted the concrete floor from 2 meters height. The fact that there was some stairs right in front of us...didn't helped either.
Anyway her face was now quite fucked, glasses broken, blood everywhere , so she calls her mother , they take her to the emergency room , somehow they patch her up...and after 3 weeks of looking like a sad watermelon she was good as new.
She was cool about it though , didn't tell her mother what actually happened , instead said she slipped on the stairs , and refused for me to pay for her glasses . ( I convinced her to let me pay for her medication at least )
<bot>: Tried to stand up , I'm weak as fuck , dropped my friend from 2 meters , face fucked...somehow she still talks to me
