I don't know the answer, I can explain it time and time again to my dad that if the phone does not display a name then don't answer it but it won't go in. He has had long conversations with the 'have you had an accident' people even though I tell him to just put the phone down.
He is too polite to do this and just accepts that if someone says something then it must be true because 'why would they lie'
I have contemplated taking his bank card from him for safe keeping but I just can't bring myself to do it.
