We all have this one friend, this one friend who is notorious too late. From which we already know that you shouldn’t appear on time at the appointment – just to save yourself time and anger. It is no problem for me ten minutes too late. I am patient. The academic quarter of an hour is also perfectly fine. If you get a message or a call that someone is in a traffic jam, does not drive the subway or you have forgotten the wallet at home and had to turn around again-also okay. The girlfriend, the friend at least apologizes and warns you. And it doesn’t happen all the time.
