writing a letter to a friend about buying a computer (письмо надо написать)

Hello my dear friend, Alexander!

I did not write to you for a long time as I was busy.

I bought myself a new computer. I now can play on the computer in special games. I can work on the computer. I learned to work in many programs. I have practical experience working on the computer. I like to teach parents how to work on the computer. I can teach you how to work on the computer. We can go through a computer game together. I also bought virtual reality glasses.

I am waiting for your arrival.

Regards, Alexey!
