You're absolutely right, still it's funny to think about.Nah, "I'll be there in 6 minutes" means I just checked my GPS, and what it said my estimated time of arrival is. "I'll be there in 5 minutes" is doing it without a GPS, because they know where they are going.
Or texting them: "We need to talk", and then turning your phone off for a few hours.You can instantly stress out anyone just by shouting "catch".
