Hey (picture someone in your head)....... just wanted to see what you're up to today?
It's me again, condition number one: you must invite whoever just called you on your trip, be at the cafe across the street 6 sharp.
Phone call contuies.. Hey uhh I actually won a free trip and I was wondering if you wanted to come along...
YESS! That's great, I'm so excited I'm going to go pack. See you soon!
