Nothing like a nice, warm blanket.

Pickle and Pearl, wandering through South America, have found a colourful market in Bolivia. They were reminded of another market place in England in the city of York where a balloon lady sold (what else?) balloons, (see issue dated 27 April 2006, "In my beautiful balloon"). In this market, in the city of La Paz, the Indian lady sells many coloured blankets. Because the location of most of Bolivia is in high, bleak table land most people wrap themselves in blankets to keep warm, hence a blanket seller.
As we are in the mountains....
UN POCO MOSCA upon the peak/ I know you never learned to speak/ If you did you'd be a freak/ And all we'd hear would be a squeak!
Note:- Not the usual AABB scheme, instead for a change, AAAA.
