A music box

I have a music box.It was a present for me by my lost grandfather.He was very kind for me,so I loved him very much.
When I was a child,I could not meet him frequently because my family lived wide apart.When we saw after a long separation,he gave to me a small brown music box.I was very very pleased.Then,I came to listen to it before I went to bed.It's sounds made me happy,and reminded my grandfather.But as you know,sound of music box become weakly and weakly.delightful melody gradually turns sullen tones as rate become slowly.It made me sad,but I like the melody.
This music box still remain in my room.But I am listening less it now.However,It is very important thing that I got from my love.
