Oh, that's pretty harsh. [Ren sounds more amused by it than anything, though.] Though I don't think you're wrong about it either. It must be sad to be the kind of person who doesn't even have one thing they can put their all into...

[Ren can be a bit lazy about things he isn't passionate about, but then, he's made quips about being pathetic for that before. So he can go along with this train of thought merrily enough, since when it comes to important things, he definitely feels it should be all or nothing.]
