Письмо другу овеликобритании на английском языке

Hello, my dear friend Sem.
I decided to write to you about the UK where I went.
The weather is rainy in the UK. People are very friendly in the UK. I speak English in British. I saw a tall and beautiful Big Ben. I visited the royal palace. Many Stewards in red uniform and a black hat are on the streets of London. I rode a boat on the River Thames. You come to me. We will have fun. Youll stay on my hotel. We will visit many beautiful places. We will walk on the streets of London. 
With best wishes, your friend Sali.
