Sean: We're leaving before 8 AM, we decided
Jeff: So early?!
Steven: Yes, it's just we want to see sth more than yesterday, if you want to sleep till noon you can join us somewhere afterwards
Sean: we want to go to the Guggenheim in the morning 
Steven: then we will have a lunch break and probably proceed to the city museum
Jeff: I want to go to the Guggenheim!
Jeff: to come to NYC and sleep instead of going to the Guggenheim is a disgrace 
Sean: Your choice really, but we won't wait for you this time 
Jeff: Couldn't we just leave at 9?
Jeff: they're opening at 10!
Sean: ok, we can leave at 9 but not later
Steven: yes, 9 is fine with me as well
Jeff: so come to my hostel at 9, I'll be ready
Steven: ok!
Steven, Sean and Jeff are meeting at 9 AM at Jeff's hostel. They are going to the Guggenheim Museum. The hour is quite early for Jeff, but he is motivated to visit the museum. Steven and Sean will not wait for him if he wants to sleep longer.
