Asking for and Giving Advice
What should I do -- should I leave or should I stay?
What should I wear to the party?
Should I call him/her?
You shouldn't do that!
You shouldn't tell her/him
You shouldn't park here, you know?
I wouldn't do that, if I were you...
I would call him/her...
Rule no. 1: Give advice only if you're asked to!!!
