The thought of if he was holding them while waiting for his girlfriend, what kind of 'relationship' than is considered close enough to do such 'intimate' favour for the girl?

Mummies, would you object your teenage sons holding bras for girlfriends??
I would object my teenage son having a girlfriend in the first place.
