Jargon type metaphor, but it works: every party brings their own luggage to the proposed union, then each person unpacks it until there is a big heap of stuff in the middle of the floor. To get any sort of understanding, the significance of each bit of stuff needs explaining. That is so hard.
We used to use it at Relate, with couples, when I was a counsellor with them. It does make sense but, in the case of a wedding, could also make for despair; everyone's "stuff" has significance to them alone.
In the end, we do what we can, with empathy and in an attempt to understand that other people are different. Which is probably the most difficult thing...
