I'm a member of three different groups, all of which meet occasionally in the evening. Since two of the groups only get together about every six weeks, it's unusual for all three group meetings to occur in the same seven days. In fact I can't remember it happening before. It's happening this week though - hence the trigger for this blog post "Different kinds of group, different kinds of friendship".
The group that meets pretty much every week is probably the most straightforward. We've been getting together for many years to play badminton for a couple of hours. It's great. I hugely enjoy it. It's warm too - we're friendly and we joke a lot. We encourage each other and we're very competitive as well. However with most of these guys, I hardly meet them except to play badminton. I could tell you very little about how their lives are going, or about how they're usually feeling.
