Dear twins

 Do you remember me,  I am  father  Christmas? I am not so sure
because you didn't write any letter to me, well maybe you where
very busy with school and activities, no problem.

  I am very busy too but I wanted to write you a letter. I have
been struggling  the polar  bear for a  while, he is driving me
crazy, Polar decided to start a plantation for producing coffee
beans from the snow!

  He told  me that  since in  polar  region  agriculture is not
popular doesn't means is not possible.
  Well oho oho! Polar tried to plant coffee on the snow but the
result was frozen  seed, Polar  keep  saying  if  Francesco and
Aurora manage to have tomato growing  in the house  i can  grow
coffee in north pole! Can you picture the Polar  irrigating the
field at  frozen temperature? He  spend  a lot  of time melting
snow in the house, then running outside for giving water to the
plant  but  he  never  manage  because  all  the  water  frozen
instantly,  basically  when  he open  the door  and get out the
water is already frozen and now the Polar bear's field  is full
of ice blocks!

  The entire  situation  is getting  funny,  polar is getting a
little bit nervous and he want me to include in this letter his
request of help, can you  explain to  him  that  cultivation on
polar region is impossible?
