If you dont have any friends, look in the mirror, and what do you see? A smile or a frown? If we walk around with a chip on our shoulder, we drive people away. Conversely, if we are polite and friendly, we attract others to us. If you wish to attract birds, scatter bread crumbs, if you wish to attract friends, scatter seeds of love.
