You won't be late

You won't be late,
I do believe-
My sky can wait,
You'll spread your wings.

But I believe -
Pain's hard to tell...
First fly you leaved,
I knew you fell.

Were only swinged,
Your wings, I knew,
Won't stand unwinged
Your different you.

That's only why-
Without the wings,
Across the sky
There is no way.

You'll understand-
I do know why
I don't know when,
I don't know how.
