Thinking about my post on not leading, this came to mind:
A home group that I was part of needed a 'leader'. An older woman, one of the long time members of the church was told she was the leader.
Discussing it with us, she was flipping between being horrified and being overwhelmed. She didn't know what a 'leader' was. No one told her.
However, we figured it out: she kept the roster and made sure we all knew the venue as it varied from month to month.
That was all. She was our organiser. She was great at it.
