Thanks very much to everyone!
Also, I failed to mention that it is VERY rare for our house to be totally empty. Whether it be my sister, mom, or dad, someone is ALWAYS home. My mom is currently unemployed and my dad is lucky enough to be able to work from home! I would be able to put a second cage/play gym in the family room where he'd get fresh air from the windows and interaction with people all day while I am away. Another thing I saw mentioned was a girlfriend or social life. Really, my social life is very slow, for two reasons. One: I've had the same girlfriend for around 3 years, I know, CRAZY for my age. But I am very happy! Second: All of my close friends have left for college or have actually left the country for various reasons. I have not, nor ever plan on, going to parties and drinking and socializing in that manner as the stereotypical college guy is thought of. I really want a Grey for a friend to be around all the time, like my dad has with his yellow lab. I do realize I have to face facts, which is why I haven't gotten one quite yet and have been seeking advice from people with more knowledge and experience such as yourselves.
Thanks for all the replies everyone! Not sure if what I have just explained has changed any variables or not with me getting one but any other replies would be greatly appreciated!
