Stop to think...

There are several times in life when I stops to think; when a warm but uncomfortable feeling resonates in my heart, when I have watched a film that has hit home, or read a book that opens up another compartment in my brain, or I fall upon a precious moment shared between two people quite by mistake, or I let myself dream about what could be. At these times when I stop to think; I am sad because I know who I could be, sad because I wish I had done differently, sad to know what will never be.
