Dear Tony，
Thanks a lot for your invitation．I'm （76）really sorry I can't go to your house on Saturday afternoon．I'm （77）taking a vacation on the beach on Saturday and Sunday with my friends．On Monday，I'm studying for my science test．I feel worried （78）aboutit．On Tuesday，I'm going to my （79）uncle's house to visit him．He phoned me last week and （80）told me that he missed me very much．On Wednesday，I have to look （81）my grandfather because he is very old．On Thursday，I'm helping my parents with some （82）housework．And I have a guitar lesson on Friday （83）afternoon．My mom thinks I can do much better in the guitar in this way．
On Friday evening，I would like to go for a （84）walk with my brother in the park．Can you come and （85）join us？
Write soon．
Yours，
Jessica．
