apushutayid- there are parents of boys who insist on meeting the girl before their son meets her. I don’t think it’s a common thing, but it happens.
My friend’s sister once ended up meeting two sets of parents in the same week. She had dated a boy 5 or 6 times and met his parents, but the shidduch didn’t work out. A few days later, a boy said yes, but his parents wanted to meet her before she went out with their son. So she met his parents.. B’H that shidduch worked out, and they are married with a baby.
