In aam zindagi(reality), I won't let my daughter alone to any man's house where he lives alone. Even if he is a relative or close friend, I would find it creepy if any man asks that.
But this is Anupama zindagi where a Maa is proved to be real by the mamta meter of world's besht Maa and the depth of mamta is decided by having a Maa in one's name... So yea, it's not odd to hear such dialogues in this zindagi
