Some people are genuinely curious about birds, but sometimes just start with the "How much did you pay for her?".
That disgusting comment is made far too often. How can you not realize how rude that is to say to someone? They wouldn't point to your handbag or watch or jewelry and ask how much you paid for it, or anything else in your posession for that matter.
One time I had repair people come in who I didn't know, and one of the guys was staring at the Ekkie I had then, and asked how much she is worth. I told him someone gave her to me, and she is terminally ill

. I felt like saying, "why? so you can break in later and steal her?"
Well, sometimes it's not all that sinister. Sometimes it's actually a
"I want one of those, but I heard they were expensive... I wonder how expensive."
"Where did you get her" is another frequently asked question... as well as the ever popular "Does it talk/make it say something."
That being said, I never like to talk about what a bird might cost/resell for... DON'T WANT TO GIVE ANYONE ANY IDEAS...
That EXACT scenario happened here on Halloween. Ripley was out, flapping on top of his cage rigorously, front door was open (storm door was shut), and folks had a clear view of his antics.
We had the doorbell disconnected because of the dogs, but the SCREECHING folks at the door almost sent me through the roof.
"OMG, they have a parrot." ...Next thing they moved over about 10' and were looking straight through our big living room window, all 8 of them.
"OMG, they have 4 parrots." By then I was at the door, trying to calm them down, because not only were my dogs going ape-$hit, but all 4 of my fids were screeching at the 'peeping toms'. :11:
The man insisted he had to have a parrot. He asked so many questions in under 10 seconds, yet didn't give me a chance to even respond to one before popping the next one.
So...I told them to sit tight, I was actually gonna bring Ripley out.
Once they saw him up close and personal, half of them backed away. FAR away. Wife: "Holy crap, look at the size of that beak. Does he bite?" :30:
"Yes, he removes digits regularly, has children for dessert and screams bloody murder all day", was my response, with a HUUUGE grin on my face. :21:
I told them if they were TRULY interested in learning about parrots to come back any time during the day, with no entourage....and left it at that.
