“I’ve changed my mind．I wanted to have a telescope, but now I want my dad back．” Lucien Lawrence’s letter to Father Christmas, written after his father had been knifed to death outside his school gate, must have touched everyone’s heart．Lucien went on to say that without his father he couldn’t see the stars in the sky．When those we love depart from us, we cannot see the stars for a while．

But Lucien, the stars are still there, and one day, when you are older and your tears have gone, you will see them again．And, in a strange way, I expect that you will find your father there too, either in your mind or heart．I find that my parents, who died years ago, still linger （留连） in many of my dreams and that I think of them perhaps more than I ever did when they were alive．I still live to please them and I’m still surprised by their reactions．I remember that when I became a professor, I was so proud, or rather so pleased with myself that I couldn’t wait to cable my parents．The reply was a long time in coming, but when it did, all my mother said was “I hope this means that now you will have more time for the children!” I haven’t forgotten．The values of my parents still live on．

It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care．Would I have been as ready as Philip Lawrence has been to face the aggressors（入侵者）, and to lay down my life for those in my care? How many people would want me back for Christmas? It’s a serious thought, which gives me pause．

I pray silently, sometimes, in the dead of night, that ancient cry of a poet “Deliver my soul from the sword and my darling from the power of the God．” Yet I know death comes to us all, and sometimes comes suddenly．We must therefore plan to live together, but live as if we will die tomorrow．We live on, I’m sure, in the lives of those we loved, and therefore we ought to have a care for what they will remember and what they will treasure．If more parents knew this in their hearts to be true, there might be fewer knives on our streets today．
