Makes perfect sense
She in in the process of embarking on a dramatic life changing event.
She has been preparing for years for this (based on the summer training).
She is an adult. Maybe not legally, by the "minute", but she sure is
picking up the responsibilites as one.
She is leaving home.
She is in the army.
She has probably been sexually active for a while.
AND YOU THOUGHT YOU COULD ASSERT PARENTAL CONTROL TO KEEP HER FROM FROM SLEEPING (ok, HAVING SEX) WITH HER BOYFRIEND?
When she won't be seeing him again for quite some time?
When she might actually DIE before coming back (a realistic belief)?
I can easily see it from her viewpoint.
And even if she hasn't been sexually active yet, this was probably planned as the magic moment. The going away present. Her graduation into the real world.
Reminds me of a Dilbert comic (from memory).
Dilbert talking to Dogbert.
Dilbert says he's created a web porn filter.
Kid, Timmy in the background is trying it out.
Dogbert: You really think your programming skills can withold the
onslought of a million sex crazed teens?
(background noise: POP)
Dilbert: Was that the sound of Timmy eyes popping out?
Dogbert: You know, if you put a little woolen cap on a snowball it can last a while in Hell.
