Different schools will have different preferred methods of doing this, but in general it is a good idea to identify a title by some form of typographical alteration, particularly underlining or italics. Quotation marks may be favoured by some, but could be ambiguous. As an example:
I for one am distressed by the pomposity of King John.
Here we cannot be sure whether it is the character or the play which is pompous. Let's try it another way:
I for one am distressed by the pomposity of "The Life and Death of King John".
Now we cannot be sure whether the title is pompous or the play is. But if we write
I for one am distressed by the pomposity of King John.
there is no ambiguity.
Notwithstanding the above, if your teacher or professor tells you to use quotation marks for the title, go along with it. They are usually extremely opinionated on this subject and it is not worth your time to argue.
romeo and Juliet
No, your quotation is wrong. The correct quotation is "Romeo, Romeo wherefore art thou Romeo?" The word "wherefore" does not mean "where", it means "why", so the quotation means "Romeo, Romeo! Why are you Romeo?" Juliet is asking why she had to fall in love with Romeo, the son of Montague, since she is supposed to hate all Montagues.
Well, that isn't the exact quotation from the play, but that is a paraphrase of Romeo talking to Juliet in Shakespeare's play (Romeo and Juliet). The original line is "My name, dear saint, is hateful to myself / Because it is an enemy to thee."
At his writing desk.
One example of when it is appropriate to use both italics and "quotation marks" in writing is when you are citing the title of a book or a play within a sentence. For instance, you would write: She enjoyed reading Romeo and Juliet by William Shakespeare.
The title of the play, "Romeo and Juliet," should be italicized in the sentence: The students attended a production of Romeo and Juliet.
No
The writing took place before the performing.
cause romeo is dead
She would brave the ghost of Tybalt to be with Romeo. She makes drinking the potion a sort of toast, by which she honours Romeo by drinking it. She has become totally fixated on rejoining Romeo at whatever cost.
"And so did I. Well, we were born to die."
"Making stars to line the heavens" is not a quotation from Romeo and Juliet. Perhaps you are thinking of: "Give me my Romeo; and, when he shall die, Take him and cut him out in little stars, And he will make the face of heaven so fine That all the world will be in love with night And pay no worship to the garish sun.
