To Max Today we had to let you go, It broke our hearts in two, We had to leave you at that place, Alone and feeling blue, The only thing that we could do, Was to drive back home and cry, For we just couldn’t keep you, No matter (无论) how we tried, You’ll never be forgotten, As long as we two live, You gave us all the love, A little dog could give, Looking at your small hutch, We know you are not with us, From this moment on, We begin to miss you much, We’ll think about you often, And wanna know where you are, And in our hearts we’ll hear your bell, Tinkling from afar (远处). 小题1: The writer wrote this poem to ________.
