So I'm going to the Laufey Concert next week (humble brag) But the problem is initially I was gonna go alone but then my dad told me that his officemate's child is coming too and since she's a minor I could accompany her. I have seen posts about people meeting up inside with friends with different QN but I just want to ask what's the protocol when with a minor do we follow her QN in entering or mine or whichever ones lower. Thanks
