After 3 days of work we have an 8 foot ceiling going all the way across our kitchen.
Which doesn't seem like a particularly huge accomplishment, but that's how construction goes. We've been involved in building a house before, and it seemed like day after day after day of not much happening, then all of a sudden the finishing work started and woosh all sorts of exciting things going on.
Also, although the house hasn't seemed overly dusty (other than the carpets), I swear I've breathed in a ton of dust.
The cats have been having a bonding experience under the bed while all of this is going on.
