David has a hobby of sculpting and has been bringing in extra Simoleans because of it. He also mastered the scuba diving skill.
David eloped with Belinda because they didn't have enough Simoleans to throw a wedding. His sculptings earned extra cash for the family. David is also somewhat interested in a woman in town called Nicoletta Lombardi, much to LifeSimmer's dismay.
The family might move to Isla Paradiso due to David's high skill in Scuba Diving.
