The thing about me, if you haven't figured it out by my response
   to your "I care... why?" is this:

   I don't do sarcasm very well. I don't read sarcasm into people's
   words often unless they tell me, or unless I stop and think
   about it. I don't do much well at all really. I actually _do_
   appreciate the time you took and I'm glad I've had the time to
   spare to engage in conversation. Be well, Good Sir, and I'll let
   you have the last word.
