I was just about to remark that he sits way too well for someone from America, but seeing that he's doing it purely out of sheer will makes me truly admire him. Daniel, sitting still for 30 minutes is impressive! Great job!
I think the difference between a family room and a living room is formality. A living room is more for entertaining guests and the family room is more for just hanging out with your family. But practically they are interchangeable.
the difference between a condo and an apartment is whether the tenant owns the unit they’re living in. in a condo, each resident owns their space, but in an apartment they are just renting from a landlord/company
Here's a fun fact, the 'living room' is a modern re-branding of the 'parlor room,' which in the European tradition was the more formal reception room in the house, hence why it's in the front of the house. The re-branding comes from that, amongst other reasons to take visitors, it was where you would have the viewing of the dead.
