I broke my co-worker's personal computer.
A few weeks ago my co-worker came to me for help with her computer. She uses her personal computer for work and it is in bad shape. The computer is cracked and is about seven years old. I write my boss and ask him if we could replace it. He said we can't because she already has a desktop which she dose not like to use. Last week she came back to me and said that my co-worker said to install our copy of the new OS on her computer.
Her computer hard drive died when I was installing the OS update. I tried for three hours outside of work to restore her hard drive. I was able to make a back up of her hard drive before it totally died. I lent her one of our computers and she gave it back to me because she didn't like it. I told her that I am done helping her and that she needs to pay for a new hard drive.
Today she ate lunch with us. She started crying when she was talking to my department about how I her computer broke and I didn't even notice. My boss talked with me and I told me that I need talk with her about how I handled myself. I told him I will talk with her and I don't need him to be there.
How should I have behaved?
