aha!,
That other Apostrophe.

Apostrophe (Greek ἀποστροφή, apostrophé, "turning away"; the final e being sounded) is an exclamatory rhetorical figure of speech, when a talker or writer breaks off and directs speech to an imaginary person or abstract quality or idea. In dramatic works and poetry, it is often introduced by the word "O" (not to be confused with the exclamation "oh").


That would be funny also if I were the actor in a play and I lost that apostrophe.
O, Me. O, My. What do I do know?

Instead of:
"O death, where is thy sting? O grave, where is thy victory?"
It would be O death, where art thou? I was talking to you!

I have always struggles with where to put apostrophes and commas.

Oh, that's easy. Put the apostrophes up and the commas down.

Quite interesting! I learn and learn...

If you had not lost your ἀποστροφή, but just your punctuation apostrophe, would your post have been something like:

My lost apostrophe! I miss it so much...

"O death, why thou hast done it? O grave, is it buried in thine cold heart?"

E pregando e piangendo io mi consumi
Rendetemi il mio ben, rendetemi il mio ben, Tartarei Numi.

<Added>

Sorry, I mean:
O death, why thou hast done it? O grave, is it buried in thine heart?"

<Added>

Or should it be: O, death, why hast thou done it? ...

Also,
E pregando e piangendo io mi consumi
Rendetemi il mio ben, rendetemi il mio ben, Tartarei Numi.

-->

And praying and crying I consume myself,
Give me back my beloved, Gods of the Underworld

Of course, from Monteverdi's Orpheo and Euridice

I guess I'm cheap. I grab a small piece of paper, tear off a section, and wrap it around when the thing its too loose. Quick and effective fix.

The original poster DID say it was very loose. Tracing paper usually works best, though, or origami paper. (essentially 35-40# paper - very thin)
