DEAR ABBY: Do you think it is appropriate for a brother (age 21) and a sister (age 17) to share the same bed? The siblings each have a large, comfortable bed of their own, but frequently wind up sharing. This is very troubling to a dear friend of mine, who is their stepparent. It seems the biological parent is hesitant to discourage the behavior, and only reluctantly admits it might be inappropriate. -- JUST ASKING IN HOUSTON
DEAR JUST: I am mystified at the attitude of the biological parent, who appears to be ignoring a possibly incestuous relationship. Of course it's not appropriate. The "children" should have been sleeping apart since well before puberty.
