Regardless of the environment, there seems to be an overwhelming need for close and/ or intimate association in some sort of capacity.
For some people a group or a crowd is not necessary, just one such association can be sufficient, but must be there or they feel the void.
It is truly an existential need, and some have a hard time getting satisfaction and keep meeting many other entities in the quest for fulfillment.
The episode illustrated in the original post simplifies the phenomenon, but overall, associations and their variety of flavors (rasa) could really be a main underlying motivation for endless transmigrations.
As one who is seriously struggling on the path of inSelf Yoga, should a time come, when I find companionship in the transcendental sound, I will consider that perfection in my life.
