I'm not annoyed that he overreacted to a Facebook post. I'm not annoyed that he obviously invaded her privacy by going onto her browser, loading up Facebook and looking at her posts because he doesn't trust her. I'm annoyed that he's got such issues that he's not facing.
The chores that she lists aren't normal chores for a teenager. I can't think of many teenagers who are asked to spread manure across their gardens or asked to run a mop or brush through their house everyday when they come in. I suspect that the fertiliser is like a couple of times a year, otherwise it's weird that she'd be doing it regularly into late winter. But the cleaning the floors thing sounds weird if they have a cleaning lady. He says she's not a cleaning lady but he just says she's a lady that comes in and clean their house. Well that's a cleaning lady. If the thing he says after that clarifies something, I don't know what it is because his accent was way too strong for me to understand then. But yeah, they're a cleaning lady. It's like saying "Just because that guy bakes doesn't mean they're baker". It clearly does.
On to the bigger points. He's spoilt her. He obviously has. He just spent $130 on her upgrading her laptop. Which he then goes and shoots, a clear misuse of a gun, and then expects money off her for both the upgrade and the bullets he just wasted. Rather than donating it like a previous poster says, he just lets off some steam by destroying a perfectly functioning laptop.
He also complains she doesn't have a job. If he wants her to get one, why hasn't he forced her into getting one like "You either get a job or I'm not letting you have your phone and laptop"? It's obvious he even thinks of her as a materialist because that's all he takes away from her. Objects. Nothing like saying "You're grounded, you can't go see your friends". That speaks volumes about her.
He also says "Why should I pay you for chores?". Well if he's going to ask her to do this sort of stuff then... yeah. Pay her. Give her ten dollars a week. Why? Because if the rewards she's being given are upgrades to laptops, she's being spoilt. However, if she's given the money and then later does it herself, she'll feel like she's earned something. Nothing feels like a better reward than buying something yourself that you saved up for. I don't know how to explain it but it just is.
The worst thing about this is the video is sadistic to the core. He's hurt that she posts something on Facebook about him and his wife but here's the thing. Nobody pays attention to Facebook. It might be the talk for about a week tops but then it's gone. Dusted over, never to be heard from again. Sure, I'd be angry if somebody posted hurtful stuff about me on the internet but it's not as widespread as people think. Who cares about one 15 year old girl annoyed with her chores? It's so pointless. But rather than talking to her about it, he prints off her post, reads it aloud in a video and shoots her laptop about ten times and expects money for damages. He then says he's going to post it to her wall where she won't be able to see it but all her friends will. So not only does he know it's going to hurt her when she finds out what he's done to her stuff but it'll also embarrass her at her school when other people find out. It's wrong on some many levels, I'd be tempted to call it abuse if went one or two steps further.
tl;dr This girl will now grow up to resent her father because he blew his fuse at something so minor rather than talking it out.
