I was passing a large chain fast food restaurant lately when i noticed a large pizza was 22Euro.This got me thinking about the old Oscar Wilde quote" some people know the price of everything and the value of nothing". I have to admit I'm guilty of this also. I would think nothing of buying said pizza but would think an apple tree of the same price might be a bit expensive. While i would have forgotten the pizza after five minutes the apple tree would possibly produce apples for my great grandchildren.
