There is a subtle difference between an acqaintance, a faie-weather friend, and a tru friend. An acquaintance is around you merely to enjoy your company, a fair-weather friend flatters when all is well, but a true friend has your best interests at heart and the strong guts to tell you what you must hear, whether you like it or not. If you're lucky and smart, you will recognize and appreciate your true friend, and will be able to keep safe distance from fair-weather friends and acquaintances.
