My word is her voice obnoxious. I've decided to turn off the voice sounds for the whole game just so I won't have to hear her constant "YOO HOOOO!" every time I do some shopping or what not in central city.
A simple and low-key "hey" would suffice. By far the most obnoxious NPC I've come across. Worse than Elder Scrolls NPCs who get upset just for you passing by.
