It's hard to watch others go.
Once you've been around long enough, you become accustomed to the fact that life is fleeting for most. They arrive, they live, and then they die and their footprints fade so quickly it was like they had only existed in a dream.
In the beginning, you don't realize it's going to hurt so much when they leave. The first one one perishes and you are still surrounded by other loved ones to help hold you up. The second one goes and it's the same story.It's when it gets to five or six that it really starts to sink in.
At first you try again. Find new friends, new loved ones, new relationships to surround yourself in. You immerse yourself, forgetting that you had a previous life, allowing yourself to be completely reborn under new circumstances.
The cycle repeats itself.
After a while, you lose interest.
Too many others have come and gone. You become the withdrawn, socially inept lurker, that the kids whisper about and the parents walk past hurriedly, pushing their children along. It's no use anymore. There will never be another who comes and stays, for good.
Willing or not, they all leave in the end.
