Have you ever noticed how you look at things differently after having a loved one serve in a war zone? It's not unusual, in fact, it's quite common. Some people have secondary PTSD; some are just more aware of what it is that they could have (and sadly, some did) lose should their loved one not make it home. Others, while grateful theirs came home, miss the innocence and memories of who that person was before spending time in a war zone.
By the way? That box of chocolates? Sometimes you find one that you never tasted or experienced before and it takes you on a new journey. I can't watch Forrest Gump with the same affection I once did, but now, because my own “Forrest Gump” has been to war, I can love and appreciate it even more. Let's help you find the positives in those adventures with your own box of chocolates, okay?
