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.
