I'm just imaging a Sim with the sad moodlet sitting on a box, in a room full of other boxes, overwhelmed and eating spaghetti.

Maybe various skills could play a role in how these actions go?

A low handiness skill could mean you run the risk of breaking your furniture or assembling it incorrectly. A low athletic skill could cause you to scratch or put holes in your walls. A low charisma skill might mean you can't get people to help you without the promise of ordering pizza.

For context I was thinking about The Sims 2's IKEA Home Stuff DLC and how in The Sims Bustin' Out for the GBA you unpacked your furniture from a crate. It got me wondering how moving mechanics would work in the Sims 3 or 4.
