I thought that would be the case. No, you shouldn't pretend to be bad at things just to make him feel better. There's nothing wrong with having different skill sets. Katherine and I are... sort of similar, except she just doesn't care. To be honest, I think I'd prefer your brother's way of dealing with things. At least that way I'd know if she even actually cared about me -- or anything, for that matter.
Let me guess -- these "things" tend to be on the shadier side of legal?
