Input: Text: i was a high achiever as a customer service rep with a large company's hr department, believe it or not.  i specialized in taking calls that had escalated from other reps and de-escalating them.  if you've ever asked to speak to a service rep's supervisor because they weren't making the grade, well, those calls are what i specialized in.

i could deal with those calls because i knew my stuff and could generally keep my wits about me with angry callers on the line.  that's not to say that i always dealt with my own anger in healthy and useful ways, however.  far from it.  

one (very stupid) thing i did to release some anger from time to time was to curse at a customer once they had disconnected the call and were no longer on the line.  that brings us to our story.

i had a particularly tense call with a gentleman with whom i wasn't seeing eye to eye.  i will admit that i came into the call irritable and didn't handle myself as well as i normally would have.  not my best work.  

we went round and round on the topic at hand until i heard silence and saw a popup window on my computer screen indicating that the call had been disconnected.  callers didn't often hang up on me, but i wasn't surprised to find that he had.

i had developed a very dumb habit of responding to such hang-ups by saying 'fuck you too,' and that's how i responded to this hang-up, which provided a moment of catharsis.

this all-to-brief moment of catharsis was interrupted and ruined by the very same gentleman speaking to me, still on the line, responding to what i had said.  i had assumed that he had hung up.  not so.  a glitch in my phone software, one that i had never before seen, mind you, had told me the call was disconnected when it really wasn't.

he was responding to harsh words that were spoken on a live phone line with him on the other end, but were absolutely not intended for his ears.  my intention, however, seemed to be a moot point. he was (quite understandably) livid.

my apologies and pleading explanations were no help in my effort to save face.  nor was the fact that my voice had shrunk to a shaky, pathetic, nearly childlike tone from that moment.  he wanted to speak to my manager, and after some time i relented and put him on the line with my manager (it would have done me no good to deny him this, ultimately). 

suffice it to say, i now have plenty of time on my hands to learn some better anger management skills.
