Kuan,
How would this guy get father of the year? What exactly did he teach his daughter? She apparently had a rant on her Facebook which she didn't expect to share with anyone but her friends; so then he has a rant and tries to embarass her while attempting to stifle his obvious anger. He then takes out a gun and shoots her computer to prove what point? That he is like King Kong?
Maybe this is why his daughter goes to Facebook to vent. She's a teenager; get over it. Let's hope she doesn't try to stifle her feelings with drugs.
And Miss Manners would also not approve.
