One thing to keep in mind with these little green attitudes is that they are all individuals. What works for some may not work for others. Some are cuddly and some are not. Some are very active and playful and some are not. Like mentioned before, the key is building a relationship with your bird.
Birds are way too intelligent to put in a cage and leave there to eat seed and look pretty.
Also, birds are not showpieces. Take that bird back to where you bought it and get yourself a pet rock. There are many opinions on this and no one opinion is correct. Actually, a combination of everything is really what you want. The bird's main diet should usually consist of some sort of pelleted diet.
