It's not 'natural' to speak well, eloquently, in an interesting, articulate way. People living in groups, families, communes say little - have few verbal means. Eloquence - thinking in words - is a byproduct of solitude, deracination, a heightened painful individuality. In groups, it's more natural to sing, to dance, to pray: given, rather than invented (individual) speech.
