I think that’s reasonable though. Families don’t have time to get to know a nanny in depth before hiring. They have to prove their trustworthiness through their work...
besides, it's a person from his friend who introduced him to the babysitter so it's not a complete stranger with no clue.
all the comments above are right and i must add that you never really trust anyone with your child no matter how much you know the person. plenty of horrible stuff has happened to children because of over trusting parents
He doesn't trust him yet he leaves his kid with him who he claims to hold precious to him. How logical...
