Well, I'm always an enabler.
Have you hecked into the "basic" personality of a parrotlet?
"Parrotlets in general are feisty, affectionate, and willful. If someone wants a great companion they should keep only one bird, because a pair of parrotlets will probably bond closely to each other to the exclusion of the owner. However, parrotlets are dimorphic and easy to pair up, and they do enjoy each other’s company. They can also be kept peaceably in groups in large aviaries, but it’s best to keep them separate from other species. They will quibble and fight over object and territory, so keep that in mind.
Males and females make equally good companions depending on the individual. Companionability has much less to do with gender than it does with handling and socialization. Hand-fed parrotlets are very friendly, especially if the guardian takes the time to keep handling the bird. If left alone for too long, a single parrotlet can lose some of its companionability. The Pacific parrotlet, in particular, does not understand that it is a tiny bird, and has little trouble challenging other animals and humans.
The mutations are said to be more easy going than the nominate color (green), but they are also said to be less hardy. This may be a result of inbreeding. Because of the small size, the parrotlet may seem like a great companion for children, but kids would probably be better off with a budgie or something in the Neophema family. The parrotlet can be temperamental and feisty, and its bite packs a wallop."
If you decide a parrotlet isn't for you, I would go for a cockatiel.
