I was Christian Growth Chair. of our LWML.
I noticed some people came and didn't return. Questioned one about it and she said she just couldn't hear what was being said and felt odd sitting there absorbing nothing. We have a mike but not all people are conversent with mikes so would ask who ever is speaking to speak very, very, loud.
Another think I noticed. We had one speaker who had us do something instead of just sitting and listening. After all, in church we do take part. Suggest finding a way to include people in a discussion or some sort of activity rather then just sitting and listening.
