92 year old enforcer

My little ole 5 foot 6, ninety-two year old dad has recently moved from home to the community care center at the VA. He is by far the most mobile of the residents there. He shuffles a little but generally gets around well using a walking stick for extra support. The other day I went to visit him after work. I looked in the day room but he wasn't there. I looked in his room but he wasn't there either. Then I thought I heard his voice. When I looked across the hall I saw him sitting in a wheel chair shaking his walking stick in the air. I called him and he scooted out of the room, using his feet to move the wheel chair. When I asked him what he was doing in the other guy's room, he said he was telling the guy in the bed to be quiet and not wake everyone up at night. What? He said that the guy made lots of noise at night just to be annoying and that the nurses couldn't do anything to make the guy shut up. Sooo, my little ole dad decided to take things in his own hands. Huh? I have only heard stories about how helpful my dad was to everyone he meets-well, maybe he thinks he is being helpful now.
