What is Wrong with People

Man I just can't figure people out these Days. Well I have a Co-Worker that I pretty much help out all the time when she has questions or needing help dealing with Computer Software. Most times she forgets her keys and I'm usually the only one that goes to her rescue. Well Today she pissed me the blank off. I had to put together a newsletter for work and I had asked for information weeks ago from each department to send out to their staff. Well one of her workers sent me some information but it wasn't nothing that I needed for the newsletter. Well all I did was send an email back requesting for information from her and two others in her department. About 10 minutes she calls me from her cell chewing me out for asking for information and didn't even give me a chance to speak and hung up the phone on me. I turned my chair around and looked at my boss cause he sits right behind me since the phone was on speakers and he heard everything. So I said to him WTF is going on with her I didn't do anything but send an email for information for the newsletter. After this what she has done she can forget about getting help from me from now on she is on her own. She will need me before I will ever need her.
