Anyway parrots are amazing animals, but unless you have lots of time to play with them, don't get one for a pet. I spend over an hour a day interacting and playing with our parrot.
I'd just add that in addition to your excellent advice, that some parrots can be a lifetime investment too (or even beyond, i.e. you need to provide for them in your will!).
Probably like hearing a joke in an unfamiliar language.
I had never even assumed that an animal that small could live that long.
BBC made a 30min documentary "Kea the Smartest Parrot" about the birds, but unfortunately it has been removed from YouTube. There are some clips still there... and if you look hard enough you can still find it somewhere on the internet.
Have you seen the parrot's and crow's assumption track record?
