If any vampire has ever been some what decent to you, they were likely neonates, Brujah or Anarchs or the other dregs of vampiric society. Some Prince's might not allow you to stay there. If you've been a vampire for a while, most everyone you meet treats you with fear and suspicion - or worse. You are clanless in a world where clan means everything.
The life of a Caitiff is extremely difficult, and unpleasant.
