A group's culture isn't what it claims to value, but what it actually tolerates. If you say punctuality matters but show up five minutes late, you've just redefined the culture around lateness. That small contradiction becomes the real rule.
Your contradiction is your culture. So the things that you tolerate, we can say we're a very punctual group, and then I get started at 8:35. I just set the wrong tone. Just for the record, I should have started right at 8:30. On time every time is what the DEC says, but I decided to let it go 5 minutes later. So now if I said I'm on time all the time, you would look at me and say, you're a liar. That's the culture. Even 5 minutes makes a difference.
