Time can't be owned. Often, it can't even be controlled. When 2 people decide to meet at a certain time, that time becomes holy. It needs to be worshipped. It can't be disrespected. The appointed meeting time is a holy duty for those who are supposed to meet at that time.
When a holy duty is not performed, you feel guilty. You hang your head in shame. Those who are regularly not punctual have lost shame. They have become shameless.
When you can't respect the other person's time, it means you don't respect, or value that person. Respect the time even of your subordinate, or your worker. It shows you value that person.
Next time don't blame the traffic. Plan to reach every meeting of yours 30 minutes in advance. Respect the other person's time.
