I sing when I feel good. When I sing my most favorite songs, 1.
I feel even better. Sometimes when I am listening to music 2.
and to the song words, I feel that it is specially written for me. 3.
A good song always makes me feeling something. They 4.
help me get through with the day. I also like reading. I used 5.
to avoiding poetry until an e-pal told me that I should recite 6.
poems and not to look up the meaning of the words. 7.
At the beginning I felt quite strange. Now I always lock the 8.
door. Read aloud gives you a good feeling when you are sad. 9.
When a poem is finished , I close the book and my sad is gone. 10.
