I personally prefer parrots over every other type of pet, as I find I have complete empathy for their situational reactions. If happy, they talk a lot, and sometimes need to scream. Their idea of a good time is tearing shit apart and coming up with games like "Throw ball on floor and wait for owner to get it while calling 'come here' ".
They develop instantaneous crushes during which they have no idea who their previous crush was, but when they get tired they always want to go back to the same person. Biting is sometimes a really fun game. When they get horny they will first try to have sex with their favorite living thing and when that doesn't work, experiment with every toy in sight.
Lastly, these animals are smart enough to hold a grudge when appropriate. My little bird is in love with my boyfriend, and acts happy for about 5 minutes when he comes back. Then he starts looking for an opportunity to lace his ear open for leaving him. Once this is accomplished, it's back to the loving.
