Another vote to wait till school is finished. Greys are flock parrots, and they dont handle being alone for extended time well. I mean there is a chance this particular one will occupy himself with toys and cardboard boxes , etc, while your gone. You might have to literally teach him to do that ( like play with the stuff yourself, tear boxes up, do some foraging puzzles). Parrots want to be with their 'flock', which is you, if you adopt one. In a family setting, perhaps your spouse might work from home or just be home , and even if they are not your birds "person" they would still be part of the 'flock'. I'm sure you would not want to get a fairly well adjusted grey parrot, only to have him descend into boredom and start plucking feathers to kill time until you get home. And the other folks are right, there is graduating, getting a job and potentially being around even less. Parrots are wonderful companions, more then just a pet like a dog or cat, but they require lots of work and some sacrifices on your part. And they AINT cheap to maintain, by any means.
