Don't be silly. We use mirrors only to check our butts and tummies to make sure we adhere to Section 2 of the nationally mandated, federally approved, Patriarchy Code of Conduct Handbook: "Approved Looks for the Male Gaze." We are all miserable and hate ourselves because we aren't at peace with our bodies, and we can't love ourselves because the patriarchy demands us to look our best. If it were up to me I'd rather let myself go, grow some nice pubic hair looking, thin, spotty beard on my neck and play Overwatch all day, but because society pressures me I do pushups and stuff :(
