About the article "The New Normal (TV series)", section "Premise".

Candidate passages:
When Twain and Lange had become romantically involved in the mid 1990s, there was criticism of their relationship: claims that the age difference was extreme, and that Twain was solely using him to further her career.
In essence, the critics did not expect their relationship to last.
Twain disagreed with these criticisms and wanted to address them in public and this led to her writing "You're Still the One".
In this ode to the union between her and Lange, Twain explains how she is glad they did not listen to the critics, as if they had done, look at what they could have been missing.
Twain and Lange divorced twelve years later in 2010 after 17 years of marriage due to an affair between her husband and her best friend. 
The language in this play moves from fast to slow.
It goes from fast paced dialogues to slower monologues.
In the normal conversations the characters are often interrupting each other.
Quickly moving through their conversations as if they know what the other is going to say.
It slows back down when one character really has something important to say.
Sherman also uses singing within the dialogues.
Those lines give a little insight on what is to come.
The singing also attempts to hint at Reuben to see what he is missing.
“So baby love me/ Love me tonight…Tomorrow was made for some/but tomorrow may never come” (Sherman 81).
This is first heard when Reuben and Sarah are having dinner and it seems to be foreshadowing their romantic relationship.
But it is also heard later in the play and could be seen as a call to Reuben to focus on the present.
