Kage: Hm...good question. But there has been one person who lasted quite a while. She was a 20 year old woman I think. The only reason I didn't find ger boring is because she didn't react to any of my antics in the same way most people do. She didn't seem scared or afraid at all actually, it was interesting.
Me: Interesting huh?
Kage: Yeah. The only reason I started to get bored of her was because after a while getting the same reaction over and over again got boring. She did last a month though which is pretty impressive.
(I kinda just made all this up)
