In correcting a non-native speaker's English, I'm not quite sure what to do with the expressions in quotes below. Should they be capitalized, as they are below, or should they begin with lower case letters?
I already heard the correct expressions were "Thank you for talking to me" or "Thank you for talking with me."
I'm unsure because the function of the quotation marks here isn't really to quote what someone said or might say, but merely to demarcate the expressions from the rest of the sentence and each other.
