English Grammar Hi friends, as a native speaker which one would you use in this context "after I have explained it or after I explained it" and why? I am pretty sure they pretty much mean the same thing but I don't know which one native speakers use more often. Here is the question. A. I am sorry to bother you. They have accepted John's application after you have explained it to them, so I think they might accept mine as well if you help me explain it. B. I am sorry to bother you. They have accepted John's application after you explained it to them, so I think they might accept mine as well if you help me explain it.
