My dad recently had a birthday and happened to be in China for it. Check out this story he told me when I asked him about his birthday.
Some friends brought a birthday cake with a typical Chinese gizmo — a flower-shaped candle holder, where you light one candle in the middle, which then results in the entire gizmo opening up like a lotus flower, auto-lighting more candles and squeaking an electronic Happy Birthday tune in a continuous loop sequence. Trouble is, it does not come with instructions on how to turn that tune off. We could not figure it out and ended up throwing it in the public garbage pail on the floor, where it merrily continued squeaking loud enough that I could hear it around one corner in the aisle and the thick metal door of the apartment. So, I am sure, could the neighbours. This device was obviously inexhaustible, as it was still squeaking happily away this morning, but by now from a garbage bag all tied up and waiting to be collected.
Most likely, the garbage truck driver or the staff at the dump are still enjoying the merry tune this very moment. If this were not happy, noisy China but Germany, the police would likely have come in the middle of the night on a noise complaint.
