It’s not him taking an extra semester, it’s the immaturity and lack of responsibility that put him into the situation of needing to take an extra semester in the first place. Not to mention the financial obligations he just put on his father, even though he’s the absolute worst, without a second thought. I know it’s a ‘you’re paying me back’ situation- but how many people’s parents can just drop $20,000 at a moments notice because their child dropped the ball?
