Mum has carers twice a day. She usually lets them in the front door herself but if the carer arrives when she's still in bed there is a key to the back door in the keysafe outside which they use. I have hidden Mum's back door key as she was inclined to leave the doors locked, with the keys on the inside, meaning no-one could get in in case of emergency. On Thursday she had a new carer for both visits who locked her in the house and put the key in the key safe. Mum rang me to say that "someone" had been to the door, locked it and taken the key away. I have to confess I thought it was a ploy to get someone to go round as her daycare had been cancelled on Thursday so I just reminded her where her spare key was. I live 80 miles away from Mum so I can't just pop round. Yesterday I visited Mum and discovered that the regular carer had found the front door key in the keysafe. So Mum was right after all! I called the agency and although they were very apologetic they did say that they had some clients who were locked in between visits. Surely this can't be acceptable?
