Leave the car keys by the wall socket. The point of my original post wasn't to say that 'even with reminders, it can still be forgotten' ... it was that it's just part of getting out of the car. Sometimes I forget to close the charge port door when unplugging (we had a series of posts on that & if you can reach back from inside the car to close). I just think it's unlikely, based on actual experience and not supposition, that people will forget to charge. can it happen? Sure! But I don't think it's going to be a common occurrence. Give the woman some credit. She remembers the kids most of the time, I assume.
