funky sister friend (2), Sisters and Friends by lesley432 Get this custom t-shirt at Zazzle Another take on sisters and girlfriends. Where I end...she begins. I have this terrible habit of leaving my sentences just hanging in the air...incomplete. I can't ever seem to hold my concentration long enough to complete a simple sentence. Both my sister and my best friend complete my sentences for me. We just carry on a beautiful conversation, never missing a beat. That is how well they know me. That is what I mean...Sisters and girlfriends. We complete each other. When I am weak, she is strong. When I feel low, she lifts me up! When she is low, thank goodness I lift her up. For some reason, we are never low at the same time.
