Last night I was woken up at 1 am  by screaming, terrified screaming.  I apparently jumped out of bed and began screaming myself (I don't wake up well out of deep sleep).  Ben had been sleeping down in the family room.  Josh woke up in the middle of the night, he's not a very good sleeper, and went out to the family room to watch TV.  B was there so J woke him up and started lecturing him about sleeping in his own room and telling him to leave.  B in turn threw a playschool farm at J.  The chase was on. B (14) ran screaming up the stairs towards our room with J(16 and twice as big) hot on his tail.  Apparently my screaming startled them both into silence.  Whatever it takes for peace  :).
