I have a lot of useful things that are very dear to me. But the most favorite thing-cup. Why is it just a cup? Because it is unusual and has its own history, remembering that, I smile. Two years ago, I had a friend who is now, unfortunately, moved to another city. Before leaving, he gave me this cup. Which reads: "a good friend" and displayed my photo. And always when I drink tea, I remember a friend. This is how this thing became my favorite thing!
