This… seems a bit naive to think your parents will call you first every single time they want to do something special with their computer. It makes me think of parents that assume their teenagers aren't doing anything stupid because they are confident the kids are sharing everything with them.
Anectode: My in-laws are renting their property through Internet. They occasionally receive calls by interested renters and they successfully manage it by themselves. They are almost in their 70's. One day someone had a payment issue and asked to pay them differently, asking for account information so they could send the money directly. They managed to trick them into putting their card number on a fake website displaying the agreed-upon amount. They lost about 100€, the bank couldn't revert the transaction for some reason.
Parents only call you when they are unsure of something. The problem is when the scammer manage to convince them everything is normal, which is exactly what they are good at.
