I've got the impression that LSEs usually don't have friends as their universe limits to their families. They might know people outside their family but they are usually not friends; merely, acquantainces.
I know Deltas in general are very individualistic, somewhat reclusive. But it seems like the rational Delta pair (LSE-EII) sees friends in a very different light from the irrational Delta pair (IEE-SLI).
¿What do you think?
