Wondering about strange people

Why are some people like a dog with a bone? They can’t seem to let certain things go and I don’t mean things you’ve done to them just things you’ve shared with them. For example: I was having a bad day at work and I was driving around as is my job. This person calls and asked me how my day was going his going fantastic! The weather is kind he likes sunny and hot I on the other hand do not like this weather it is uncomfortable…and I believe I have written about it in the past needless to say he notices that I seem distracted and I share that I was just sent to the Boston office to handle some business and found it to be in total chaos, that the person we left in charge there had not been following the system and was basically running things his own way and doing as he pleased. I expressed the only reason why I was upset was due to the fact that I had to solve it organize it and get it back in play, sort of get it going in the right direction, when I realized that this was my job and I was not getting paid enough to do this when all I really wanted to do was fire him and retrain someone that would keep it running smoothly and stick with the system…because it works. He always wants to do his own thing and work it to his advantage and screw everyone else so how can you work with someone like this. Who can’t follow or refuses to follow orders? In my book you send him packing “I regretfully have the unpleasant task of informing you that your weak ass services are no longer needed!!!”
I can’t all I can do is report to my superior on Monday when he returns from vacation and let the axe fall where it may but if no change comes about I will go back to my previously quiet existence and enjoy not moving up the stress filled ladder… this conversation (venting) happened on Tuesday and I have all ready moved on to my schedule and what I need to do, when the very next day this person calls me to ask “Hey did anything get resolved?” I answered; no I told you that all of this has to wait until Monday when my boss gets back from his vacation. Then he proceeds, “wow dude you must be pissed, aren’t you?” and at that very moment I realized that, that was what HE wanted he actually called to piss me off again or to get me going….I saw this and quickly said, nope I’m good, all will take care of itself I just have to relay the facts and let the chips fall where they may. That was not enough for him he kept at it pressing, prodding and poking to see what he could get….didn’t give it to him just said “took care of business did what I had to do now it’s in someone else’s hands.” Still to my amazement he kept looking but I did not give it to him and just told him that I had to go and hung up……strange how some people are living through others failures instead of their successes.
