For my experience, holding a camping activity is like having a dream. No matter how wonderful the dream is, there is an end. That is the time to say goodbye. Maybe traveling is also like holding activity. Even it is sad, you still have to leave the memory behind. That is not heartless, but the beauty. You had creat the best memory. It can't be better. Just like the sequel of best selling movie are always disappointed. You should know where to say stop. Don't make it unperfect because of the feeling. Maybe it is a little unreasonable. But I thought it is an art.
