How long should you wait......
Basic scenario
You've arranged to meet someone/ a group of friends, your dangerously early once again!
The time has passed and still they/no one has arrived....
How long( and be reasonable), should you wait before you finally give up and go home?
I usally wait 15 more minutes (depending on the weather and my location) before finally giving up and dragging my carcus back home....
what about you ?
