Sigh

I know you notice when I sit and sigh
(Of course, I try to make it obvious).
You often stop to make me tell you why,
But I can't answer - it is always thus;
You want to know - I want to tell you, too -
But when I sigh it is specifically
Because I cannot tell you what I want.
From this small revelation you may see
Each caring question is a kind of taunt
Reminding me of what originated
The sighs you noticed. I think if you knew
The reason why your questioning so grated
You would not ask me anymore - but then,
Not asking would just make me sigh again.
