Many years ago in the hippy era, I worked as editor for a very tiny independent magazine, Freedom Today Magazine. The staff all worked for basically nothing, and we ate out of a big soup pot (I did have an apartment of my own) and we worked all sorts of crazy hours, but we would take off to go see a movie or go skating. Sometimes when work got too hectic, we would all get up and boogie to the latest songs until we would collapse laughing. We were living the hippy life in a good way and we all loved it.
Every time I would go into the kitchen I would see this absolutely magnificent floor to ceiling house tree that had been made from a cut-down eucalyptus branch. It had little branch stubs coming out all over it and there were cups hanging on each stub or other kitchen things that were truly unique and fun.
From that day on, I never forgot that house tree, and I determined that all my houses or apartments or mobile homes would always have one and I did that.
