Really sorry to hear that! I think it must have been their green (or blue?) parrot that I had an amusing conversation with a few months ago. "Hello!" I said. "Allo!" it screeched back. "Hello!" I said. "Allo!" it screeched back.
This went on a few more times. Then, having spent a minute marvelling at this bird, I turned around and walked off. From behind me came the screech, "Goodbye!"
I don't often laugh out loud in public but I did then.
