cobblestone

'..narrow streets of cobblestone.' (Simon & his Furunkl)
What the hell means 'c.'? – Ah, OK.

Me and my 5 brothers & sisters were driving to school on our bicycles. We shouted, but we couldn't understand our neighbour.
My bicycle often had to be repared.
The school was about two and a half kilometers away. I was seven or ten years old. The icecream was very cheap.

So I could have said: »What is this thing called 'cobblestone'?«
(How many mistakes? Excuse me.)
