Okay, first, why shoot it? The parents obviously bought it since they said the daughter doesn't have a job, so the dad really just shot his own computer. Nuke the hard drive, sell it on Ebay.
The daughter had some pretty legitimate reasons to vent on Facebook. I'd think that some sort of allowance is in order if you're going to make your child do chores. If not, guess what? They're going to hate you for it.
