I've always had a pretty tough exterior and had a pretty stiff upper lip but these past few weeks I've realised just how fragile the human body can be and how a tough ones mind has to be to overcome obstacles life hands us but sometimes it can be to much even for the strongest of folks.. my tough exterior has broken and my stiff upper lip has turned into watery eyes and a quivering chin as I feel helpless while watching my poor pappy fight this tough fight.
