Heading to the airport and not even a block out, I spurred this conversation from the rents:
"That's it, I want you to buy her at least three drinks on the plane."
"Fuck no, one drink does her in! I'm not carrying her sloshed ass off the plane!"
On a related note, Mom has learned two words in Czech - hello (ahoy), and shit (hovno).
This is going to be an interesting week.
AFTERTHOUGHT: My Czech word of the car ride was most definitely 'krootsi!' - "for Christ's sake!" This is not how you're supposed to use a phrasebook.
