I have sadly seen mothers who only attend one meeting and never come back, and I suspect that this might be the reason. I want to single out the idea that promptness tells people that they are important. There are many different personalities at work in a Group. Some are always early or on time, some are chronically late. Lateness occurs for many different reasons.
Some Leaders are always late to their own meetings.
Lateness is not necessarily deliberate, nor is it done with malicious intent for those waiting. We can all agree, though, that waiting is frustrating and annoying. It makes us feel helpless. Even those among us who are chronically late have experienced these emotions when we stand in long grocery store lines or wait at a doctor's office. Our children often accompany us to meetings, and we are all pleased when they can recite the advantages of breastfeeding, sometimes as young as three or four years old.
