Being available - hey, would you like to hang out and grab a cup of coffee sometime?
Being desperate - hey, would you like to hang out and grab a cup of coffee sometime? (after the other person agrees) Shall we go out now?
Being stalker - hey, would you like to hang out and grab a cup of coffee sometime? (after the other person agrees)
That's wonderful! I've made a reservation for us at 4pm tomorrow at XYZ cafe, where you like to have the Cafe Mocha with lots of whipped cream, along with chocolate chip cookies. I figured that 4pm would work for you because it takes you one hour to commute from office, and it's 2 hours before you go to the dinner party hosted by Sally tomorrow.
