I thought the same Si vs Ti. I only describe how to do something in detail if someone asks me to (but then it's easy to do).
I don't solve puzzles/code for fun, that might be the Ti with Ne.
I was not intending to be condescending, what felt like that to you? If I seemed condescending to you then what on earth was Bertrand's stuff? Something even worse... But I tried to take it as a joke instead of getting annoyed. Now if that was condescending to you that I found it funny, not my problem.
