Dear Ben,
I’m very happy! Ihave spent my holiday in London. It's one of my favourite cities. We went there with my classmates and our teacher. We saw a lot of interesting places in London. First of all we saw Big Ben and the Houses of Parliament, the Thames and the Tower of London.  Just imagine it!  Then we went to see  Westminster Abbey, Trafalgar Square with Nelson's Column and the British Museum. My dream came true, because  we took a ride on the London Eye and  watched  the Changing of the Guard near Buckingham Palace. Unfortunately, we didn't  visit St. Paul's Cathedral and Hide ParkI've learnt a lot of useful information and took a lot of interesting photos. I'll send you some of them. 
Keep in touch. 
Best wishes,
Vlad
