Argue about vs. argue over

A.) Timmy argued with James about his curfew.

B.) Timmy argued with James over the store’s return policy.

The sentences above use the same verb (i.e, argued) but different prepositions (i.e, ‘about’ and ‘over’).

Please help me figure out what is the difference between sentence A and sentence B.

There are some verbs that go with several prepositions. You can say to argue with somebody about something or over something. Both versions are correct with the former being more common.[YSaerTTEW443543]
