Dear Casey,
You asked in your last letter about my spare                               
time activities. Well, I like much more than one,                                 76．_____________
such as painting and model making, so my favourite                           77．_____________

and it is a great fun! Dancing is not difficult. If                                79．_____________
you want to do it good, you need to find a good                              80．_____________
dancing teacher and taking lessons regularly.                                      81．_____________
