Also, even when you do know what you're going to say, it doesn't matter. It's a linear game with a bad illusion of choice. Every option is a way to say the same thing in a different way. And the dialogue isn't very well written or emoted(?) well. 
It's not like this:

"Sir! Sir! Raiders just kidnapped my son! Please help me!"
A: [b]CALM DOWN[/b] Calm down. What happened? 
Accepts quest.
B: [b]WHERE?[/b] Where did they go? 
Accepts quest.
X: [b]NO[/b] "Lady, I don't care." 
Denies quest.
Y: [b]IGNORE[/b] 
Can talk to Lady later about quest.

It's more like this.

A: [b]WHERE?[/b] Where?
Accepts quest.
B: [b]WAIT HERE[/b] *Robotic voice*Wait here. I'll get your son.
Accepts quest.
X: [b]REWARD[/b] *Emotionless*What's in it for me?
Accepts quest.
Y: [b]JUSTICE[/b] *Robotic voice*They will be brought to justice.
Accepts quest.
