Context: Honestly , not a day went by where my Nana would n't call me about getting rid of my moles . I would tell her , ' Nana , I have had them my whole life , they have not changed , there is nothing to worry about ' . That was not satisfactory to her , and after a few months of these ' talks ' I succumbed to the pressure and made the appointment to get them removed .
