I've seen some sentences in which go seems to have the same sense of get...
He's going crazy... This could mean either "He is behaving crazily" or "He is becoming crazy". You can use "getting" instead of "becoming".
She's shy... She's going red. "Becoming/getting" are both possible.
I'm going mad... As above.
Josh went angry This is incorrect. You could say "Josh got/became angry".
my questions are: When should I use go or get? When exactly can I use "go" istead of "get"?
Is it correct? too informal? Does it have the same sense as "turn"?
She's turning red
Thanks in advance!
