Parrots are very expressive, and if you live with one for months/years, you'll learn its moods. Not hard to see how a parrot responds to something new.
I have three, and they are a lot of work. Assume a couple hours a day. We make toys for them every day. The noise, the mess, the neediness. It’s a lot. They are a joy, but I don’t really don’t suggest others to get any.
