Questions Galore!

Where does grief end,
When does joy start.
Who crosses the line,
Who even doesn't start.
Is there a fine line,
Between the boundaries.
Is there a colour,
Between all the colours.
Whom to have faith on,
Whom to believe in lie.
Whether to take revenge,
Whether to die as a fly.
Its a questionable world,
Whom to ask,whom to answer.
