"Definitely not," Tali replied, making a bit of a face. "There's the reapers, the collectors...my own people were at war with the geth--an artificial intelligence that we created hundreds of years ago. Then there are the batarians, the vorcha, the krogan...none of them are very friendly. The volus are mostly benign, but they'll rob you blind if you allow it. What you would likely consider the friendliest races would be the asari, the elcor, the hanar, the salarian and, well, the quarian. Your own people had a conflict with the turians shortly after first contact, but I think everyone's had a conflict with the turians, at some point."
