Input: So I was in high school one day in my engineering class, and I got to work on a project with one of my best friends.  The project was to build an original Rube Goldberg machine. While we were thinking of ideas, I picked up a PVC pipe and started talking.  While messing around she playfully tried to tug the pipe out of my hand.  I tugged back, saying “Quit it” because I was already in a work mood and didn’t really want to mess around.  She tugged back, harder, and when she did, I lost my grip around the pipe and since she was pulling so hard, she fell back.
I started laughing, as one normally does when their friend makes a sill mistake, but what I didn’t know was that her phone was in her back pocket, and she landed on it when she fell. The phone had some pretty large cracks, (which made sense, because she didn’t have a screen protector and she is a little overweight) and it was not turning on.  I was still laughing from the fall, and I said I would pay for the phone no problem ( it was a Samsung Galaxy S5) and that period I was met with strings of curses and insults like, “Go **** yourself”.  Throughout the rest of the day, whenever we passed, she wouldn’t say anything, and would just give me a cold stare.  
It has been 2 days since the accident and she still has not talked to me and I have paid her $80 of the 200-300 that I owe her.  Yesterday, I found out that she was talking to my other friends and acquaintances, and trying to convince them that I pushed her/threw her phone, none of which I have done.  When I talked to said friends about it, they said, “you should go apologize to her” and I told them no.  They told me that was f***** up and that I should be ashamed of myself.  
I feel that I have been nothing but respectful (minus the apology) while my friend has been nothing but cold and immature.  I don’t think that I have to kiss her a** since she told all those lies and I’m in the middle of paying for it.  Was not apologizing really that bad??

not apologizing for my friend's Broken Phone even though I paid for it, and it was Kinda her fault
