Wealth, connections, merit, life. Superficial, though it's not really your own life? Yet another tragic case of conformity.

Superficial relationships

Friendships can appear not even to friends from outside. This occurs especially frequently!

For me, the definition is that there needs to be MEANINGFUL converse/activities. Classmates rarely, if ever, fit that criteria!

Walking together is not enough. Eating together is not enough (eating while talking increases choking/multitask).

Friendships from being forced to do certain things, like school classes, are an ILLUSION (however,r if you genuinely like that person and they like you back, it's fine?)

There's also the reverse:

One common mistake is confusing PROXIMITY with RELATION.

Yes, we do make friends that are "convenient," eg school. So do prisoners. But it does not guarantee.
