My dad....
My dad was a good dad and I loved him...until I was 13. He then started REALLY bugging me to study. He also started hating my new intrests, like Police chases, Rock/rap music, and other things like that. He would really piss me off, too. We also argued alot. He said he was sick of his son doing "unproductive" activitys. What made my dad turn into a first-class jackass? Is it normal for a dad to suddenly change like this.
P.S. At the time, he was 49.
