me: When is your flight tomorrow?
mom: 9:40
me: That's so early. We have to wake up so early to get you to the airport on time.
mom: When's your flight leave?
me: Later than yours! let me check. 10:30. When do you want to get to the airport?
mom: An hour early. 8:40.
me: Okay, it takes 45 minutes from here.
mom: Let's leave at 7:00 then.
me: But then we'll get there before 8! That's 2 hours early!
mom: What about traffic?
me: It's a holiday!
mom: Well, we have to check out and everything.
me: This is annoying! Do you want to leave at 7:00 or do you want to get there at 8:40?
mom: I want to get there an hour early.
me: So we don't need to leave until almost 8!
mom: I'd rather leave at 7.
