I had this thought today that if I was a Ventrue / Tremere / any other VtM vampire with access to Dominate, I would be very tempted to learn it up to that dot that lets you erase memories and then use the hell out of it every time I accidentally committed some social faux pas, felt like I made a fool out of myself by saying something dumb and unrelated, etc, etc. 
Tempted, I say. I probably wouldn't be running around erasing people's memories of me 5 times a day. Probably.

Damn, now I sort of really want to make a VtM character who totally does that. :D
