a) there has been girls in the recent past that have gotten married at 15 <— and then they DO get kicked out of there respective schools.
and the 17 man/child is unlikely.
thing number one- the 15/16 girl could be mature -the 17 year old boy? not a chance.
in those cases it’s a above age ( ie 22+) year old guy
that’s a tad creepy- aka a whooole other story/ issue
