PS: Often TV distorts contexts. Sometimes the contexts are somewhat blurred unnecessarily.
My wife and I attended a wedding - lovely to be there, wishing the Lord's richest blessing on the couple. It did strike me that some of the wedding party might have been more attuned to the context of a beach. Having said that, if they had indeed been at a beach, they way there were would probably have seemed perfectly normal. Context has a lot to do with it; but I guess that a lot of young people today are not quite as attuned to the difference in contexts. (Up here, a judge has even legalized toplessness in public, so I guess one ought to keep quiet about other people's weddings.)
