Confused to Continue

He is going to Bali this holiday while I have to stay here in Bandung, struggling in finishing the project of end of year activities in my church. I feel a bit strange actually. What is a friend definitively??? For what reason does friendship began??? In what season it is supposed to emerge and sink/disappeared again?? Is it an obligation for a friendship to face a season of being broken?? Do they have to?? How to resolve such a problem in a friendship??? These are the questions emerging in my mind all these days...
