1. I know a SEI dude. He's reserved but friendly and collectivistic. He's at ease in social situations involving strangers and avoids conflicts. In fact he's a highly sociable guy.
2. I know a SEI girl. She's cold, distant and egocentric, and sometimes seems to prefer to socialise with... animals. For this reason I called sometimes her "hippie ecologist" (for joking).
The girl case creates a problem : if the girl and I don't exchange information, we don't don't dualise each other, because the girl has an emotional condition which prevents her to connect with dudes/girls she don't like.
The guy is E9, the girl is E4. Fours are emotionally unstable, Nines don't. Besides, Nines avoid conflicts, Fours don't, and even tend to create them ! For this reason, there may be Gamma SF dudes which can't connect with ILI-4 girls, or Gamma NT girls which can't connect with ESI-6 (especially counterphobic) dudes or such.
