The following story is, at best, tangentially related to emotional support animals.
When I was growing up, we were on vacation and visited this restaurant where there happened to be a man making balloon animals. I was a weird kid and so when he asked me what balloon animal I wanted, I told him I wanted him to make me a balloon hat. I think I said something along the lines of "can you please make me an abstract balloon hat? as large as possible?"
It was an amazing hat. It was a tetrahedron at its core (the hat part) and had a bunch of corkscrews, flowers, you name it, stemming off of the hat base.
I loved that balloon hat. But we flew to this vacation. In the airport while we were waiting for the plane, my parents set me up for the inevitable, where the flight attendant would tell me that I wouldn't be able to keep the hat. But as we boarded the plane, THEY FOUND A PLACE FOR IT! Some kind soul had an empty seat next to them and they agreed to watch my balloon hat for me.
Mid-flight it probably scared the shit out of them once or twice as a couple of the balloons popped due to pressure changes.
I kept that hat for months (kudos to the balloon man's knot skills) until all the balloons went flat.
I wish I had a picture. I think kleinbl00's neighbor would've appreciated it.
