The day before Mother’s Day, Mrs. Berry asked her students to make a card for their mothers. She passed out paper and pieces of cloth.
Mary looked for a while at the blue cloth and began to cut it. Then she      her paper in half and began writing. When Mary finally looked at the message the teacher gave on the paper, she noticed something else. She felt her      grow hot---she hadn’t heard that anyone who didn’t have a mother could make one for a grandmother or an aunt.
As her teacher      to her, Mary tried covering her card with her arm, but Mrs. Berry gently lifted it so that she could      it. Mary sat      , waiting for her to say something, but she saw a      roll down Mrs. Berry’s face. She had never made Mrs. Berry so      .
When school was over, Mary      until all the other kids left so that she could apologize . “I’m sorry for not listening. I’ll make another card      you want. I’ll do it at home and      it tomorrow.”
    are you talking about?” asked Mrs. Berry.
“My Mother’s Day card. I know you’re sad because I didn’t do it      .”
“Mary, that was the      card in the whole class. It was so      that it made me cry. ”
Mary was so      that she ran out of the classroom.
When her father came home from work that night, Mary      to give him the card early .
On the front of the card was a      of Mary’s father, with a blue piece of cloth cut like his hair. Inside the card she had written:
Dear Dad,
I know you work really hard to be both a      and a father. I want to thank you and       you a Happy Mother’s Day!
Love
Mary
When her dad read the card he started      , just like Mrs Berry did.
