I went to the pictures with some mates once. My mates bird Lorraine sat in front of me. She was a a BIG girl with an Afro. I missed most of the first half because I couldn't see the screen. Then she got an urgent text and had to rush off. I thought to myself. Thank God! "I can see clearly now Lorraine has gone." Sorry.
