“Yea we’re leaving on the Friday night”
“Are you sure? Are you sure it’s Friday?? I swear you said Thursday”
“Nah nah, Friday”

…

“Oh you’re right, it is Thursday”
“Fuck I thought so, good thing you checked”
“Yeah, oops, hur”

…

“Which airport are we leaving from?”
“Gatwick”
“Ok, we need to book tickets for the train to get there.”
“Sweet, we’ll get the Gatwick Express, 40 minutes!”
“Are you sure? Where does it leave from?”
“Clapham.  Yeah yeah, we’ll be fine, I’ve done it before when I went to Ireland”
“Ok, well, make sure you book the tickets.”

…

“So it turns out we’re leaving from Heathrow, not Gatwick”
“Oh. My. God.”
“Yeah, whoops, ya know, I was wondering why I couldn’t find Air New Zealand leaving from Gatwick”
“grrrrr”
“Remember Georgie said it was weird we were leaving from Gatwick, Air New Zealand usually leaves from Heathrow”
“You almost ruined our holiday! I am handling everything from now on! Send me the itinerary! You’re BANNED!”

Heh.  Good thing I didn’t book those Gatwick Express tickets, they were hugely expensive.
