Read the following story then answer the question:
One day Dog and Rabbit walking through a forrest. While they were walking, they noticed a little mouse sitting by himself with his head down. "What is wrong little mouse?" said Dog. "I am very sad because I have no friends." said the little mouse. Dog and Rabbit then turned to each other and said "Do you think the little mouse would want to be our friend?" said Rabbit. "I hope he would want to be our friend, it makes me sad because he has no friends" said Dog. Then Dog and Rabbit turned back to little mouse and said, "Why don't you come and play with us and be our friend!?" they both said.
Little mouse did not know what to do. He was so shocked and happy that he did not say anything. Dog and Rabbit were not sure what to do because the little mouse did not say anything. "Well, do you want to be our friend and come play a game with us?" said Rabbit. Little mouse sat there very quietly and did not say anything. As they went to turn away with their heads down, little mouse jumped up and said "WAIT! I'm sorry, I was so happy that I could not say anything. YES! Yes I want to be your friend and go play a game!"
How did the mouse feel when Dog and Rabbit asked him to be their friend?
