Hmm..... I'm not sure what was the nature of the invitation
extended to you, but there's nothing in Christianity that says one
cannot have fun in orchard. Neither is it that Christians don't go
to Orchard for leisure activities.
Also, I've been to activities of different churches which isn't in
the church itself. But it is organised by the church and
non-Christians are told upfront that it will be a Christian event.
There are events like cycling, basketball matches, etc.
Christian events are not necessarily always at the church, but it
also doesn't mean you won't or can't have fun at one.
