I should have clarified that these are the reactions /on the bus./ I've edited the post to clarify that.

Yeah, I've noticed what you mention. Non-nelly guys that I don't know are chummy when space isn't restricted. I like it. It syncs nicely with my past interactions:

"I ain't exactly one of your gender, but we hang out together and we're not flirting, nor are we avoiding flirting."

I am told that some of the lads in rez noticed this odd interaction, but only mentioned it to each other.
