Why do Hmong couples fight doing something that's suppose to be enjoyable?

[theking]

So I heard of another Hmong couple fighting while taking a trip incident. This time it's 4 couples in their 30s that have known each other since they were teens. In fact they all got married in their teens too. So they came together and planned trip for a while and finally it was time to go and drop the younger kids off to grandma. Lots of excitements and happiness at the beginning but towards the middle and end phases of the trip, some drama occurred. Perhaps because they've been fighting so much during their marriage that it's just normal for them? Perhaps there were some alcohol involved?  Regardless of reason(s), it kind of ruin a get away trip that's suppose to be relaxing and enjoyable. Not to mention the time and money it took to plan and book things to do..

Hopefully they can learn and not repeat because it seems like such a waste of time and resource IMO.
