Nowadays there are a lot of things you "expect" people to own. Various furniture (bed, couch, tables, etc.), various tools (hammer, screwdriver, etc.), kitchen supplies (plates, bowls, utensils).
Say it's 0 AD, in the city of Rome, and you wander into a random person's insula. Is there anything you could reasonably expect to find? Anything that "most people" owned and had in their homes?
How common? Tradesperson, Merchant, freedman, labourer?
