When I was a small girl, my granny used to ask me: "Girl- what's the noise of a train?" and I answered proudly: "TschTschTschTsch!"

 

I thought, today's children would not know about this noise anymore, but on the train I met a little boy and I asked him: "boy- what's the sound of a train?" And the boy answered shy: "TschTschTschTsch!"
