Sorry to hear this ..it is always hard when 'children' raise these kind of issues ..in my case, for no reason whatever, some years ago my daughter sent me back ALL the photos she had of me and her when she was young ...no explanation ..after 14 years still no idea ..she stopped speaking to me then ! very odd …..but just a few weeks ago I was talking to my step daughter and she said she had no photos of her when she was young, or of her late mother ...so a trip up to the loft uncovered years and years and many boxes of photos my husband had kept ...so I spent many evenings trawling through them al and found loads of photos of her and her sister , mother, grandmother, dog, aunties, etc etc so I have now got a very large box and am slowly putting them al in it along with some memorabilia of her father's time in the Royal Navy and the places he visited, his medals, magazines from the ships he served on, etc etc (he is sadly now in a care home aged 86 suffering from Parkinsons, dementia and cancer...has not seen his daughter for some 9 or 10 years ..neither of them were good at keeping in touch ...sadly I cannot ask him about the photos as he doesn't even know who I am, let alone who is in the photos...obviously I have kept some since we met 1 years ago, which are relevant to me ……….so please don't take it to heart ….there may be an innocent reason for his question ..I am 71 and there are only a very few photos of me from childhood …..but I have all the memories where they matter. My brother just passed away and I found loads of photos I never knew existed in his house which bring back lot of memories. You could perhaps explain, as others have said, camera, films and developing them were very expensive when money was tight ...and hope he understands.
