Comment: Re "Too Close!":  Some readers have described the LW's lack of comfort with the brother/sister sharing of the bathroom as crazy or looney.  I don't think people who react that way realize they were lucky enough to come from a healthy family, at least in that respect.  I've had more than one friend who was sexually assaulted by a brother growing up, and in my extended family, one brother orchestrated a gang rape of his own brother.  Maybe because of my history, in my own family there were lines of privacy around intimate body care that were never disturbed or questioned, so I can imagine being uncomfortable with the situation LW described.
