"Hey, it's 24 hours before your flight back to Chicago which hopefully will not be delayed by inclement weather! Have you checked in online?"

"Have you secured transport to the airport/paid some dude in a van to come pick you up because you're too insecure to bug your friends for a ride?"

"Have you had all the Christmas presents you bought online for your family sent to their house so you don't need to be bothered by traveling with them?"
"Have you packed?"
