SHOUT OUT TO MOTHAFUCKIN' DINKIIIII
IEI Just legendary, really. Does everything the EIE does, but better. Their use of Fe is subtler, and less obvious/more to my taste. Can engage in conversation with them so naturally I could seriously never get bored of having them around. At the same time, even if I've known them for about five minutes, just being around them is quality. The only issue is that they are too few in my life!
EIE Absolutely wicked people, I find them incredibly energising and great activity (literally) partners. Very fun and great to talk to - I can talk how I want without having to "tone down" because they're completely unintimidated and actually enjoy my behaviour. I love being around them.
LSI Very good for discussion and to boost numbers at parties. Also if no other Betas are present you can have a good laugh with them about another quadra's being stupid. I like how structured, disciplined and solid they are.
SLE Not sure if I have any (may do, but they may be EIEs). If so, similar to having EIEs around. Good company and fun to be around. Can have a good laugh with them. One SLE I used to hang around with I haven't laughed as much with anyone else as I did with him. We had a kind of competitive relationship, although I never saw it as that at the time.
