My thoughts:

On a personal note, we did an event in the front yard of a home full of soldiers suffering from PTSD.  We felt so bad for these men.  They drank 24 hours a day and cried without notice.  One of the men lived there to take care of the others, he felt that it may not be safe for us there with them.  He apologized profusely for their behaviors.  We felt honored to be welcomed into their home and to let us see how they are suffering every single day since they've been home.  A small 3 bedroom home full of 12 hurting men.
