'Me' is a concept of George Herbert Mead referring to the aspect of personal identity or self that is aware of and has internalized the expectations of others. The me is guided and shaped by the culture of an individual's society or group, which is internalized and acts to direct and control behavior. In social interaction, each individual's behavior is shaped by the interaction of their socially shaped me and their more spontaneous and ego-focused I.
RECOGNIZING that the self can not appear in consciousness as an I, that it is always an object, i.e., a me, I wish to suggest an answer to the question, What is involved in the self being an object? The first answer may be that an object involves a subject. Stated in other words, that a me is inconceivable without an I. And to this reply must be made that such an I is a presupposition, but never a presentation of conscious experience, for the moment it is presented it has passed into the objective case, presuming, if you like, an I that observes but an I that can disclose himself only by ceasing to be the subject for whom the object me exists. - George Herbert Mead 1901 - The Social Self - The Mead Project.
