It goes back to the "one size doesn't fit all" rule.
I had a very interesting day today. I sat in a BigLeagues meeting all day. Most of the people were new to me and the discussion was so heated that there was a bona fide "Cuss Jar". You drop a quarter in every time you drop an F-bomb, or a S-bomb, a GD-bomb, etc... And there was well over 2 bucks at the end of the mtg. That will take some getting used to.
But not as much as getting used to my Main Male NaNoWriMo Character sitting across the table from me. Spitting image of what I had imagined for my novel, brown eyes instead of slate gray, a Maryland accent instead of Scottish - but still. There he was. I couldn't believe it when he walked in the room.
Vey unsettling.
