Hello my dear friend!

I was very glad to receive your letter. Yesterday I forgot my phone at home. It was a tragedy for me! Can you imagine how I depend on this digital. I use it every day: to call somebody, to receive calls from somebody, to listen to music, to use it as a torch, to play games, to take photos, to chat on the Internet, use it as an alarm-clock , to use it as a USB , to use it for taking notes and so on! So many things I can do with it! I can’t imagine my life without it! Of course there are some other digitals which are important for me. It is a  computer which helps me to do my homework. And  TV which helps me to relax and find out something new. What about you? What digital do you find the most important for you? 

Bye-bye.

Yours, pen friend.
