Looks like he was just charged

Tells is all we need to know.

They were sharing the same room. An 18 year old and 16 year old stepbrother.
Who thought that was a good idea?

in which case she shouldn't have been forced to do this.

But there are many families where step brothers and sisters are just like most normal siblings . They can easily share a room and be safe and any argument will be the usual sibling stuff. But there is nothing to fear. It also depends on how long they knew each other. My example is cases where they have known each other for some time.

but also what passes for an OP these days, just my opinion, generally.

Thanks to those that added links to the discussion after the fact.

A boy not a man

So I guess he could be considered a man.

Sorry.
He sure has stupid, irresponsible parents. Hope they enjoyed the cruise.
