Cast in my own mould

One thing that came back to me from Friday evening was that my friends told me when the cast was made making me me, it was thrown away. It was said in German, and took me some time to get my head around, but the essence, as I understood it, was that it's a compliment. There is only one of me, and this is a good thing. Which now when I write it, doesn't sound that good. But I trust my friends, and thinking a step further, how fun would it be if everybody were the same?
