What is the real meaning of the words 'take care' ? People used to saying 'take care' instead of 'good bye'. When departing to say either 'good bye' or 'see you later' is understandable and acceptable. What is 'take care' ? I strongly suspect it has AmE roots? When someone say good bye, in return I say good bye too. When someone say take care, what would you say? I have heard even 'good bye and take care' too. I take care of my wife and children?
