When I was in college in Florida, I bought a parakeet. Macoco. I loved that little bird so much. When I flew home for the holidays that year, I brought her with me. I put her in a shoebox, poked holes in the top and kept it secured with rubber bands, and brought her on the plane with me. No problem (well, except I made the holes too big and she almost escaped in the plane!

Had to keep them partially covered with paper.) When I was flying back, the woman at the ticket desk at the gate told me that I had to buy a ticket for the bird. I didn't have to on the way up so I was confused. As it turned out, I never had to buy her a ticket after that, either, even from the same airport, but I didn't know that at the time, so I felt like I had no choice but to pony up extra money for a ticket for my parakeet. I still remember it was $50, which was a huge deal for me at the time.
Thank goodness I wasn't being asked to do anything worse than pay extra money, but even if I had been told to essentially kill my bird, I was lucky enough to have choices. My family was close by and I could ask for help. I was also not old enough to rent a car, but maybe I could have taken a train or something. I would not have flushed my bird. Still, by refusing to do so, I would have been causing myself and my parents more stress and expense. I was lucky enough to have family who would have understood and the ability to deal with that expense and stress.
This girl didn't have the same choices - and in fact felt like she had
no choices. She obviously had difficulty standing up for herself (not everyone has the confidence or ability to stand up to authority figures.) That's called being young and scared and inexperienced, not idiotic.
