Why would you agree to a list that didn't include them? (I couldn't choose which expletives to put between why and would so you get the safe for work version.)
The reason is because this was just an initial exercise to get us talking, and I'm sure it's also meant to be a "first draft" - there's no way we would get to a final list after only one session and one try, that seems obvious to me. I'm also pretty sure C will want to see our individual lists at some point, because there's much discussion to be had around what didn't make the list, and whether either of us felt cheated by it. So I didn't get all emotional or react in any way - one of the rules at this point was that either of us could nix the other's item without explanation or defence, so it's pretty clear that this is just a groundbreaking exercise to dig up some crud for discussion. As such, it worked very well, as far as I can see so far. Next session is tomorrow evening at 6, I'll let you guys know how it goes...
