The church DH and I wanted to get married in (in the UK) wanted us to go on a 'preparation for marriage' course... 
. Which we did (in Oz). There were lots of Catholic couples there who were pleasing family/keeping with tradition etc but who's priests demanded they attend, too.
A part of it was a Saturday where we and probably 10 other couples had talks, discussions, took part in 'exercises' as couple or in teams.
Interestingly, 2 couples left after lunch... still wonder what happened there! But in the afternoon, a practical exercise we had to do involved going across to a local park that had a junior skateboard area in it. In our couples, we took turns at being blindfolded while the other talked their partner around the course.
We were obviously being supervised, but it was shocking how many couples, particularly the blokes guiding their girlfriends/fiances had to be stopped because they were deliberately putting them in danger! 'Guiding' them to the very edge of a 2' concrete drop off! Thinking it was oh-so-funny.
They complemented DH (to be) and I in how we steered each other well away from danger and edges.
When we went back to the centre to debrief, the leaders clearly said that people who felt it was okay to do that were possibly not ready to treat their partner with the trust and respect that marriage demands, in almost as many words. They 'made' us all figure that out for ourselves via 'How do you feel about how your partner guided you?'- but the message was clear.
Cue several blokes muttering and looking at their shoes.
I still wonder how many of them got married, and how many still are? I know I will sound smug at saying DH and I are 21 years in, now, but, to me, respect is at the very centre of any relationship. Posting humiliating photos on Snapchat is not respectful. And god knows, over 21 years, DH would have had ample opportunity to do the same, but was more likely to be holding my hair off my face as I threw up than videoing me!!
