I had an African Grey in middle/high school, I saved up for 2 summers to buy her...LOL Her name was Murphy.
She was absolutely wonderful - I got her too young, I think, the breeder had me hand feed her for while (weeks?).
Murphy was a sweetheart, she wasn't real social with people she didn't know but she wouldn't bite, she'd just growl and avoid them. She was a great talker. I remember I was teaching Djenga to speak, and Murphy must have heard it. So she started saying "Murphy speak! Woof woof woof - good girl!" It was so cute. She'd also call the dogs over to her cage and tell them to sit.
When my husband was sent to Germany, I left Murphy with my parents. My mom adored her, and was happy to have her. They had a spare bedroom for Murphy's cage. Unfortunately, one day the door to the bedroom was left open, and Murphy fell off her cage and was on the floor. One of their dogs got in and bit her...and she died shortly after
It all happened in a matter of seconds.
I would love another Grey one day, but right now I know I just don't have the time. They do require LOTS of attention and their diet is high maintenance. But they are worth it.
