Awkward

"It was not totally your mistake, but you are not a hundred percent clear from this. When you talk to me, you should expect some responses and since I was on the phone, sometimes my timing when I speak did not match."

"Yeah, but in my head your short 'hmm' when I was explaining was like you being rude as usual. You also said something like 'i am listening,' You might not believe it, but the timing was coincidently fit when I finished explaining and you then said something like 'just do whatever you see fit'. Your cold face when you said the sentence was like you heard me and you are just being rude as usual."
