We went to see my 94 year old nan this weekend. She lives on her own, and is almost deaf with her hearing aids in, and totally deaf without them. She WILL NOT lock the front door to her house. We told her we'd be at her place at 9.30am to pick her up. I walked up the front of her house, saw her in her front room and rang the door bell. Nothing. Rang again, nothing. Thumped on the door. Nothing. Knocked on the window. Nothing. I thought I'd try the door, sure enough it's unlocked. I walked in, shouted for her, nothing. Walked in to her FRONT ROOM, shouted for her. Nothing. She then walked out of her kitchen, looked suprised to.see me and went, "hang on I'll just put my hearing aids in".
Her front door is right on the street, right by a bus stop. It terrifies me that she lives like that. I've told her over and over that she needs to keep her door locked.
