Re: Are these Sentences Grammatically Wrong??
Mr.? Seriously? That's what the avatar looks like?
There's nothing wrong with using correct English. Shall and whom (except right after a preposition) are just about dead, but the correct use of adverbs and the subjunctive is alive and well.
Your English is amazing and I would not have known you were not a native speaker. Don't compromise just because the people around you do.
I say really good, doing terribly, and if I were. No one thinks it's weird.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
