you hear the sound and shoot. that is ptsd. i bumped my head on the covered in the kitchen and i took it out with my fist. there is my kids and my wife. but in the hell was going on with dad? there is some cans all over the floor and splinters and my hands were bloody. we hadn't a clue. we haven't heard of ptsd. so they were frightened. my wife thought it was her fault. well with just a little bit of education we would have said he has got post-traumatic stress because he's been in the war. he's not angry at us. he just got surprised and took up the covered because he wasn't thinking as part of the deal we better get him some help in some medicine. it's not our fault. my wife now -- i still do it, the other day my daughter put the chain lock on the door and i opened the door like that. it surprised me. i hit the door a couple times. my wife says you didn't take your medicine today, did you?
