I should say that from the NT perspective, I grow to love my SEI duals more and more. They are so sweet, playful and eager to learn new things. Just over the last week we have discussed the mathematical derivation of musical harmonics, global social and political trends as they relate to typology, and our aesthetic preferences in house and garden design. They seem to be open books in a way - for they are receptive to the most ridiculous ideas that might pop into my head at any time, never prejudge, and are open to changing their minds. Such curiosity is rare and very encouraging. I recently told a female SEI that she reminded me of a vacuum cleaner, because both she and the vacuum cleaner have a powerful sucking action and tend to collect a lot of material inside them. She was quite flattered by that and offered to clean me any time.
