I don't know the end, my friend!

I don't know the end, my friend
The journey will be long,
I am neither weak nor too strong,
Will you still walk along?

I don't know the end, my friend
Everything happens for good they say,
I want to be with you come what may,
If that isn't good it is still okay

I don't know the end, my friend
I see neither dark nor the light,
I don't know what is wrong or right,
Will you still walk when it's night? 

I don't know the end, my friend!!
