shaved his upper lip every morning three times with, three times against the grain

[Michael Bailey]

this does replicate the way I would say it out loud:

I shave every day, new blades I invariably draw blood.


It's like if you're talking to somebody and you've already got them
envisioning you shaving, you don't need to say "when I use" ---
instead, into the ongoing shaving thought-form, you simply add the
temporary variable "new blades"

I know this passage is narration, rather than Mucho speaking, but this
technique gives a closer, more colloquial feeling as if Mucho or maybe
Oedipa (having witnessed it) is telling me about it.
