Then I knew something was up when everything quieted down in the dining room . How suddenly everyone wanted me to clear the table . I could hear whispers and giggling , I kept trying to hold back more and more but finally I was forced into the dining room where they had an ice cream cake ( my favorite from Carvel ) They all insisted on singing Happy Birthday to me .
According to the above context, answer the following question.
What may be the reason for the giggling and the whispering ?


They are excited about the surprise .
