Answer:

Hello, my dear friend!

How are you? I heard, you was in Kyiv, Ukraine. Do you like our capital of Ukraine?

I saw your new posts in Instagram! You was in St. Sophia's Cathedral, National Art Museum of Ukraine and Mariyinsky Palace. That`s great!

I think, you met many good ukrainian people. What do you think about them? Do you have friends or foes? By the way, I like their wear styles. And you?

With respect,

Your friend ____ (напиши своє ім'я)
