I would like to add another observation

I SEI is more pragmatic and organized than myself. When an SEI plan an activity, they are very regimented in how they puts it together and gets it done. They are also not as compassionate and friendly as EII. SEI tends to take care of their own and worry less about the world at large as in homeless people and just extending compassion to people outside their circle. SEI are more oriented toward material comfort and goods than EII are. I find SEI get cold towards people and bossy when they want them to coincide with their "image" as in if an SEI is into a certain fashion or trend they will negatively reproach others who aren't also; or they may be inclined to just shut someone out inadvertently. They can be bossy unlike EII.
