Too much togetherness can be toxic; just ask the American Elm tree. A fungus called Dutch Elm Disease had literally gutted the population of stately and symbolic trees by WWII. It was later discovered by plant scientists that the problem was caused because the trees were planted too close together and their intertwined roots were infecting and killing one another. At just the right distance however, the trees will thrive, creating a complimentary canopy.
Consider your own relationships; allow spaces in your togetherness to fully reveal the other person's Wee World Wonders!
