Not nook like look,
Not nuck like luck,
But do pronounce nuke like Luke (which is not a choice for the poll).
I call my coworker Robert by "Rob"
My girlfriend's brother William by "Will"
My sis-in-law Christine by "Chris" and her sister Elizabethy is "Lizzy"
and my mother is Margaret and has gone by "Mickey" her entire life.
And, I'm from the North and say route like "scout", not like "boot."
And roof like "goof".
BUT I do say "pop" intead of coke or soda, unless I'm traveling, then I say "soda."
