So an aunt of mine suffers from Alzheimer’s and lives with her son. She's always wandering off in her dressing gown and slippers and just last week she was found wanding the streets over a mile away from the house. So I put a chain around her neck with a bell on it. It may sound a little inhumane and a little insensitive. But at least we always know where she is and that she won't go far. I mean that thing is HEAVY !
