When I was in high school, me, dad, and a bunch of extended family all went to my grandparent's house to move them out of it and into senior housing. This was badly needed for them. There was some family taking things home that they wanted. I'm not privy to everything, but there is some bad feelings over this.
At the time, absolutely no one in that family cared about genealogy. So all the old papers, pictures, etc I thought were at risk of being tossed out. My mom does genealogy as a hobby, so I'd grown up with you keep this sort of thing, even though it's not my hobby. So I took every photo album, boxes of pictures, boxes of slides, boxes of old 16mm film, and the slide projector and film projector. There was a TON of it. At the time, I kinda made an announcement at dinner, we were all sitting and eating, and I just told them that I was collecting all that sort of thing and would keep it together and safe. Ok.
Every couple years, someone asks about it, and once again I tell them I grabbed it. Last night, my aunt posts a picture from a few years ago that's the 3 kids, and as a joke I posted one of them and their grandparents from when they were kids. She'd never seen the picture. So I posted another one, taken a year or two later. My aunt facebook im'ed me, asking where I got them. So I told her, I'd scanned some of the pictures in. Honestly, I'd done more cleaning up and sorting of the physical pictures than actual scanning. I sent her all the pictures I have, about 60mg worth.
This family... sheesh. She'll forget again in a month or two, and ask again in a few years.
However, due to the other wackiness in the family - I'm not giving up these items. Sheer spite. I'll send copies, but I'm keeping the originals. No if, ands, or buts. I don't care how much I piss people off - they've earned it. Maybe they should treat my family like a member of the wider family if they don't like it.
Oh, and grandparents died while I was in college. They never knew or cared where the pictures went as far as I know.
