Example, if someone is really nice to me and I find that offensive a lot, I'd probably not have very strong Fe. If I had a lack of emotion then I would have weak Fi, not necessarily strong Ti. If I love insights then I'd have strong Ne, if I have insights occasionally or strongly then I'd have strong Ni, even if I don't appreciate where they come from. If I'm strongly attracted to logic even if I suck at it, then I'd have high Te.
If I both relate to logic, thus am good with it, and I am attracted to it, then I'd have both Ti and Te.
These aren't examples though. Eh.
What I'm lacking now is how these categorizations manifest real examples or definitions. I lack Si.
