I know there are some groups that are grieving the conclusion of Lifegroups, esp after an abbreviated season. Some folks, even in our group, are eager to continue through the summer. I personally wouldn't want to take a break from meeting in homes, fellowshipping and studying together... The reality is, like fish, after a while company begins to stink :-) As a practice, we've taken summer breaks to keep the host homes and the lifegroup leaders refreshed and ready for a new season.
So... if your group does continue to meet over the summer, keep in consideration how to help your host family out. Rotate your location. Meet at the park. Shake it up. Also, don't feel like you'll have to meet weekly. Go every other week, or monthly through the summer.
It is greatly encouraging to hear that sooooo many people don't want to stop for the summer. That says something wonderful is happening.
