Pergi ke tempat kesukaan teman Anda. Merayakan di sekolah. Adakan suatu pesta.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
Spending a day doing the things you've always loved to do together is a fun way to say goodbye. You could do something special like going to a baseball game or concert. Go out to dinner at your friend's favorite restaurant, or cook dinner at your place for a more intimate setting. If you and your friend go to the same school, have a lunchtime celebration with your other friends. Have everyone decorate your friend's locker with well wishes, and bring in treats to share at lunchtime in her honor.
