Did they also wear masks with happy smiles on them?
There should be more of these get togethers, especially for the children. There was a period of time that the youths in our congregation had get togethers and they were good fun. It was once a month and we had an hour discussion at the start where we would pick a specific topic and discuss it, there was an elder who would oversee this. It really helped us to grow spiritually as we could think, debate and discuss issues together. One topic, for instance, was about self defence and there were various views, we were able to consider different scenarious and come up with a very christian approach. We also got to know each other as human beings, our strengths and weaknesses, our fears and joy and a better understanding of each other.
We became real friends and our hello's and smiles to each other in the hall were no longer fake.
There should be more of them and without too many restrictions. Putting a bit of thought into the planning (e.g. arranging dress ups) can be good but gets to be a drag after a while unless you have an organiser who loves to do it. Most of us just love the companionship and you don't get that to any real degree at the Hall.
