Can't say it affects me much. It is too bad that the kids have to suffer because of the parent's mistakes, I will admit that, but there is also this.
I think the kids are pretty sure to hold on to at least some of the stuff that is really important to them instead of letting mom or dad put it in a "big closet" they can't get to. Sure, there will be exceptions, but I can't tell you the number of times I've found EMPTY game disk boxes and never found the game either (psp, etc). I think the kids kept those out and the games that went with them (in a big binder no doubt).
As to returning the pics, old birthday cards, letters, etc the managers tell me that about 98% of the time when they are able to get ahold of the frm owners they still don't show up for them and the managers end up throwing them away on some kind of time schedule.

In the safe lkr I got in late August there were a ton of photo albums from not only the lkr owner, but from her parents as well. After initial failed negotiations to sell her back her whole contents, I never heard from her again until two of her friends came to the facility yard sale where I was trying to sell her big furn items. After they bought a couple of pieces of leather motorcycle wear they asked about the pictures. Since a full 5 weeks had passed since I had talked to her I simply told them the truth..."I made your friend an offer for EVERYTHING, never heard from her after day one talks, and after a few weeks, all the personal stuff went in the trash. I'm not in the business of storing other people's stuff."
