Yep, my grandmother has fallen for several scams and they're all ones that prey on her good nature or just lack of understanding. She fell for one of those "this is Microsoft calling, your computer has a virus!" scams, and a grandchild in jail scam. Luckily though, she couldn't figure out how to actually send either any money, haha. But we took her cards and checks away after the second one (with her permission, she's in a weird dementia gray area where she needs a lot of help in some areas but is very capable in others, so we just always do stuff with her agreement).

The third one was the worst, she was being scammed by a home health aide claiming she was buying stuff out-of-pocket for my grandmother and needed cash reimbursement, but the aide was just taking stuff out of my grandmother's closet (that we always keep really well-stocked) and claiming she'd bought it because she knew my grandmother would just give her $20 whenever she did. She got too greedy though and my grandmother gave her $100 in a week when usually $100/month is more than enough cash, so I asked her where she spent it all and she told me about the aide supposedly buying her supplies. Luckily it still didn't have a major financial impact on her, but we honestly don't know how much that lady got from her because she'd been taking care of her for like two years and it had apparently been going on for awhile. It had just been really occasional previously, and my grandmother isn't rich but she's comfortable enough that no one's going to miss like $20-40 a month or whatever.

But yeah, it's all just been my grandmother wanting to do the right thing or trusting people she shouldn't have (and we all trusted that aide, to be fair).
