Stop Interrupting!!

Maybe it's because it's almost 3pm and I haven't eaten lunch but the woman I just met with was making me crazy! I was trying to teach her how to do something and she would not stop interrupting me. I would just keep talking (maybe even a little louder) to get her to be quiet but she would not shut up.

This morning she invited herself (without asking me) to a training I had set up with another person and basically took over the meeting constantly interrupting and talking over me.

If you want to learn, why are you talking over me?!!!
