I went to Vancouver, Canada at the age of 15 for one month to study English. My host family (Verna and Jim) lived in Richmond.
They would often take me to the Richmond Nature Park. It was fun to walk among the woods, with squirrels crossing your way.
It was there that I learned the joy of blueberry picking. The blueberry trees bore lots of fruits all around the park. It was fun to pick and eat the sweet little blue things as you walked along the shrubs.
"You are allowed to pick and eat the berries in the park", Verna said, "but you can't take them home in a jar to make jam"
There was this primordial joy in nourishing nature at first hand. You can get blueberries in packages in the supermarkets, but it is not the same thing. Devouring directly from the twigs had a flavor incomparable to any artificially prepared delicacies.
