"Есть такие светофоры: они не только зеленого человечка...

"There are such traffic lights: they not only show a green man, but also squeak when green. For the blind. The second time I see - there is a blackbird sitting next to it and beeps. In the same way - it imitates. It’s good to imitate, it seems. But only at the traffic light - red . "
