Different polarities. SLI is going to want to vegitate in his free time, whether thats at home by himself in front of a television, or at his best friends in front of a television. EIE feels fine with doing nothing,
sometimes because this calms his worry wort Si superego especially when he needs to recharge his energy. The trouble comes when EIE realizes chillaxing in front of a TV/internet is on the schedule everyday, day in and day out for the SLI. Which wouldn't be so bad the EIE thinks, if the SLI would be a little more reactive and I don't mean the chuckles and snickers and cheshire cat smiles, even the most emotive SLI leave something to be desired for EIE.
EIE will be baffled by SLI ability to seemingly hold on to feelings for years and his ability to live off a single smile or hug or shared conversation or romance, as these brief moments will not be enough for EIE.
When it comes to activities together things seem to work out fine while alone, although SLI will feel sensitive and oft slighted by EIE tastefully competitive remarks, very much unlike IEE jokes, whose pokes and jabs are never meant to cause harm. And why would EIE say these things? Audaciousness brings out the fun in others, a lesson perfected by IEE, but of the wrong kind with EIE.
In public, EIE will at first be totally disappointed that self-concious SLI hides in the back of the groups, perfectly content viewing the unfolding play from the bleachers.
EIE will find himself trying to draw SLI into the proceedings, if he is clever he would do this quietly and with tact, "Are you alright? It doesn't seem like you are having fun?" In which the SLI will reply with easily perceptive scorn "Yes I'm fine", I don't want to move" his tone perfectly saying:
why are you even asking me?!
Eventually EIE initial disappointment will turn into disdain, he sees how inept SLI behaves when put in the spotlight. The spotlight needn't be some center stage, merely as the sole person talking in a group in the living room, or around a restaurant table. The EIE has manners, even if he feels SLI is a dead weight tag along, a wet blanket, a guy who acts above it all to
cope with his insecurities, he will steer the conversation away from speech shy SLI. Next time though, SLI just won't be invited along at all.
Unfortunately SLI will notice he's not being invited out, not that he would ever advocate for his needs anyway, he will just simply sulk. The sulking will annoy EIE who needs people to advocate for their own rights, he would gladly invite SLI out if only the SLI would just say "Hey, can I tag-along?" "Of course!" exclaims EIE. The cycle repeats.
