Arthur really didn't want to grow up today. I invited the entire island to the party park next door, bought two birthday cakes... but Arthur simply refused. Back home, with another cake, he started to cut it, but... still didn't feel like ageing up. Of course, time stops for no sim... right before bed, his age crept up on him and he became a Young Adult.
Because of his stubbornness, he'll have to wait until tomorrow to change his look, but I don't think he minds that much. Monday he'll start working with his father. Maybe that idea scares him, though Lemon has never really shown the boys what he can do. Whenever he spars, it's with me, not them. Of course, they've seen him practise on the treadmill, in front of the tv and the radio, but nothing to be afraid of.
Of course, Mariska is already discussing the boy's marital status with Majora. Her romantic side won't leave Arthur alone until he gets married I guess.
The first thing Arthur does in the morning... is pay a quick visit to his mirror and dresser. After all, he needs to look good for his graduation, right? Arthur graduates with the Highest Honour. I guess skipping school too often doesn't really do for a valedictorian. His classmates have voted him Most Likely to Hack the Military Facility, though he immediately promised Lemon not to. After all, they're both in the police department right now. It would be rather awkward if he got caught doing something like that.
(It took four tries and three resets before Arthur grew up. The last reset left him with different hair and clothing. The only non-standard part was his hair... which is an EA store item.)
