Are you walking through my mind? lol that's how I felt while I was reading this post. I am in an out my introvert shell. Though that still makes me an introvert. I have two best friends from my childhood that never made me feel like I need to call or reassure them we were still friends. We see each other once in a few years but time and distance never affected our relationship.
My definition of a friend is someone who accepts you the way you are, loves you, respects you and tells you things straight to your face.
