Once again I had a negative encouter with an SEE. I think all SEE have these negative traits more or less in them.
It seems to me that they don't care about people themselves, but only care about the fun that people can support them with.
If they can't derive any pleasure from you or if they have someone else for their pleasure, you are considered to be a burden and will be dumped.
Which costs them no effort at all.
They are also great at turning things around. They want to do something or go somewhere, and tell you, we'll go there or do that, because you'll like it. As if they do it all for you, while it's just in favor of them.
To summarize, they are loyal as long as they have a need for you, don't truly care about people, and make themselves popular in a hypocritical way.
