Hi All
Ronin seems to me you missed nothing. A lease 10 years ago for how long one can only guess. The "house" over the years is filled through friends and each pays different amt..... due to room size? One can only guess? Disliked roomie morphs into smart cookie & gets lease with a built in roommate push out since it's for more rent though again one can only guess.
Mob mentality .....sounds like the Valentine's Day slaughter "Oh what a tangled web we weave"
