How sad for her daughter, who's only 12 - what a terrible age to lose your mum! Not that there's ever a good age but I honestly can't imagine that I'd have coped with such a loss at that time in my life. It was bad enough as a fully independent adult.
Hope her aunties and Bernie's friends gather around her and give her (and her dad) all the love and support they can as she enters her teens. Hope, also, that she'll be able to carry really positive thoughts of her mum with her. All the same, Bernie's still here and I don't want to start talking past tense- this time will be really precious to them all.
