Believe me, there are such, and among passers -by. They go, glance at the house or site and take out their verdict — «This is nothing, but this could be better …». It seems that they don’t care what they say there, but then you look at the lawn and think, «Yes, there really are not enough flowers …». And you begin to act accordingly. Start to break the flowerbed, you will see that watering is not enough. A flower bed will appear — you want a gazebo in front of her. In general, what would we do without passers -by?
