There is nothing worse than when you are talking to someone that you know does not care what you have to say at all.They may ask about a situation or what is going on however they interrupt you to say other things. They might be sitting on their cellphone. I keep talking although I get no response or acknowledgement that I unquestionably am talking, however one time I was talking to my friend about her HVAC system. I know it is not the best topic to discuss. I was telling her from my example of why she needed to schedule a tune up on her system. I was telling her about the one time I did not before the winter season. Our winter gets pretty brutal too, but my HVAC system had stopped working in the middle of a blizzard. They could not even send someone to repair this problem. I had to wait until the storm passed. Of course this was not something that I wanted to do. It was bad and I was trying to tell her that; She did not listen and the same thing happened to her. She never got a tune up for her HVAC system. There was a bad storm and the HVAC component could not keep up with the chilly and it stopped working. There was no one that could get to her to repair it either. You cannot say I did not try to warn her. HVAC system tune ups are essential in the fall season before the snow starts to fall.
