native and non-native language using style

Nessie

Hi,
I've read this in an English teaching site:

1.
Regional Style: It was still bright outside.
American Style: It was still light outside.

=> The "regional style" here means "Vietnamese English using style" (because this site I'm refering to is a Vietnamese English teaching site)
I just want to know whether the use of "bright" here really sounds odd and unnatural.

2.
Regional Style Would you mind posting this letter for me ? Yes, certainly.
American Style Would you mind mailing this letter for me ? Of course not. OR ( Not at all )
-> Why "mail" but not "post"? I know American people often use "mail", but British people also use "post" and I think both are all right, so I suppose the author of this just mean to distinguish the two ways of responding (natural and unnatural). Do you agree?

Many thanks
Nessie

Many thanks

Sorry Molly, I read those a long time ago, so suddenly I forgot what "regional style" here means, but then I recollected and edited it.
Anyway, you are so fast in replying, Molly Wink
