My dear friend!
I never wrote you letters, and most likely, you will be surprised to receive this letter. I hope that no distance will interfere with our communication.
I'm sorry we had to break up, but I'm happy for you. Before you now open up new horizons. "Big ship-big swimming!". You need to know that whatever happens in life, you can always count on me.
Of course, I'm sure we'll meet. You can always come to our city, and I will be very glad if you stay with me. I often recall our conversations. You know, I'm proud of our friendship and appreciate it. I am very glad that I have you and I want to thank you for your friendship.
Write to me. I miss you.
Your sincere friend.
