I respect peoples time; so if you are late for class, we would have started. There is no judgement for you being late; you just miss out.
It is just important to me that we value each other’s time and respect those who show up on time. So, I start class on time. I am known for saying at the beginning of class “if we start on time we finish on time, or earlier” 🙂
Yes life does get in the way and things are unavoidable – I just encourage people to be “Intentional”.
