Considering the time it was set
Considering the time and place this was set the south in the 1950’s I think the whole set up that Dani was to young for Court seems to contrived. Even now 17 year olds date 14 year old in high school (although probably not with any sort of honorable intent) and in was not uncommon for 14 year olds to get married in the south at that time.
I the part just played ware the Dad was telling Dani he had told her not to date yet but to bring him over for supper so the father was not apposed to her starting up with Court as he liked him better then Maureen's Date and was a good friend of Court's Dad
