<p>What don’t you understand? What’s your question? The two sentences mean completely different things. In the second phrase, talking is a noun and your is an adjective.</p>
<p>“Their walking was magnificent” is indeed the correct way to say that, although it’s really awkward. These constructions are almost always wrong, so make absolutely sure that there are no better choices. </p>
<p>“You’re talking to me” is not one of such constructions. “You’re (you are) talking to me” is just a regular sentence–“you” is the subject pronoun, “are talking” is the verb in the progressive tense, “to” is the preposition, and “me” is the object pronoun. “Your talking to me” is incorrect. The only time you could say “your talking” is in a construction such as “your talking is irregular,” and in such a construction it’s not correct to add the prepositional phrase “to me.” Like I said, answer choices containing something like “your talking is ” is almost always incorrect, EVEN THOUGH that construction in and of itself is correct, because such choices will also usually include things that make it incorrect, such as the added “to me” or an incorrect pronoun, such as “you talking is .” </p>
<p>“Your talking is irregular” = correct
“Your talking to me is irregular” = incorrect
“Your talking seems irregular to me” = correct
“To me, your talking seems irregular” = correct, but extremely awkward. You’ll never have to deduce a correct answer based on the validity of this construction alone. There will always be something else in a sentence containing something like this that makes it incorrect.</p>
<p>^ Why would “Your talking to me is annoying” be incorrect? I don’t understand. “Talking” is a gerund, but it becomes a gerundive when we add a prepositional phrase. Why would that be wrong?</p>
<p>“Your talking to me is irregular” = incorrect
Why is it? couldn’t “to me” modify “your talking”, meanining your talking is pointing to me but not anyone else?</p>
