I went through a similar situation 10 yrs ago. The way I see it, if your boy has now got a licence and is working, he may get a wider friend base away from the jws.
That happened with my boy and with so many elders having kids of a similar age, they were just itching for him to put a foot wrong, because he could have been a bad associate(LOL) for their little darlings.
They got him. Ironically, it was his honesty when asked that got him booted out. The other little gutless buggers just lied (to daddy).
Don't know about your daughter though. Mine had the brains to get out before me!
