How I will explain death to my child

The world is like a train.
On this train lives everyone you’ve ever met.
But many people have gotten off the train before you got on.
Your grandpa was one of those people.
He was my baba just like I am your baba.
Both mama and I miss him very much.
We have lots of happy memories with him on this train.
You have just missed him.
It doesn’t mean he doesn’t exist anymore.
He is just back there, where he got off the train.

No, we cannot stop the train.
Nobody can stop the train.
No, we cannot get off the train and go back there, because once you get off the train, you can never get back on.
This is why when it’s time for someone we love to get off the train, we would cry because we will never see them again.
We say goodbye when someone goes to a different part of the train too, but they can always come back, as long as they are still on the train.
But if someone gets off the train, they can never come back.

I don’t know what is there to see off the train.
Nobody on the train really knows.
Of course I want to know, but there is no way to know.
Some people have a strong belief in their idea of what is there.
Some people care less about it.
All I know is that the train keeps on moving, and we only have a limited amount of time to be with everyone on the train.
It may seem like a very very long time, but it is not forever.
Which is why baba and mama want to spend as much of this time with you as we can, and so do all the people who love us.
It may seem like forever, but it is not forever.
It will never be enough for us to be completely happy.
But it should be enough.
