I think the best composit-ions are arrived at after much trial and error and many different unrelated elements are incorporated.
In this day of instant gratification and the notion that one should just throw it away and start fresh I'm reminded of this particular grouping where the exact opposite approach was applied.
A gathering of rock, stone and plant life that would have much less impact as individual placements but when collected over the years and grouped in a seemingly random pattern around the one constant anchoring element (in this case the tree trunk) the picture comes together - it makes sense.
The same could be said of relationships. We experience and collect the shared events and memories of our time together, both good and bad, and when placed around a constant element, a committment, a wonderful composition begins to emerge in the end.
