Is it bad for a young brother and sister to share a room?

This whole debate about a Brother and Sister sharing a room is absolutely ridiculous! UNLESS there is ual Abuse in a family a Brother and Sister sharing a Room is Perfectly Fine. When a child is raised in a Normal Loving Family free of any kind of Weird Behavior visited upon the children, there is no inclination to or Abnormal behavior...my Two youngest, who are 16 month apart shared a room up until last year..my daughter was 12 and my Son was 13 when she moved out of the room to her older sisters room...when they both decided it was time. Don't worry about them sharing a room...they are fine.
