From my experience here are few problems ESE-SLI relations may have.

Major Problems:

1. Fe Lectures: ESE tends to tell SLI how to behave with people (what to say or do), which is coming from good intention to help but it just get under SLI's skin and make them see ESE as controlling, so don't lecture them

2. Fe Drama: when SLI make a mistake they feel bad & is trying to fix it, so the last thing they want to hear is how you feel about their mistake or worse how they should feel, so if they make a mistake either help them fix without the drama or take the attention away from them if it was in a social setting or there are many people around

3. Fi-Ignoring: ESE seems as if they don't understand why SLI would prioritize Fi over Fe, specially when SLI express an Fi value/interest, then ESE say something like you should do this[Fe-thing that contradict with the Fi value], this feels like a rejection of them or that their values/interests are secondary to what the group values, so if SLI express Fi value acknowledge it even if you don't agree or think they don't know what's good for them just respect they have their own values/interests & don't push yours on them

4. Always in a hurry: seriously why? I know it is because of Ni PoLR but SLI don't like to be hurried unless there is a reason

Minor Problems:

1. ESE tends to like bright colors whereas SLI darker colors (not sure if color preference is type related), this isn't really a problem if ESE don't enforce their preference on SLI or criticize SLI's taste

2. Even if SLI don't seem to be doing anything doesn't mean you can make plans for them without discussing it with them first, SLI don't like it when others expect them to just tag along without considering their opinion

3. SLI make his home comfortable for himself whereas ESE make his home comfortable for his guests, so if living togather & don't agree on what is comfortable they may have some arguements but I think It can be resolve easily since SLI focus on his own room whereas focus on the living room

Those are just my observations, and are based on the assumption that I typed ESE & SLI correctly
