My dad absolutely hates to make money and he argues with my mom every time she wants to spend a dollar. When my mom wanted to replace the heating and air conditioning unit, my dad went crazy. He came up with 10 different reasons why it was a waste of money to replace the heating and air conditioning unit. My mom told my dad that it would be impossible to live without the machine, but my dad was determined to use a couple of window units instead of paying for a brand new central heating and air conditioning unit. The first time there was a hot and humid day, my mom and dad the whole day arguing. My mom knew that my dad was overheated and miserable and she brought up the central heating and air conditioning unit once again. My dad yelled and told my mom to turn on the ceiling fan. My mom was upset and she called me on the phone. I came over to the house and I decided to talk to my dad about the central heating and air conditioning unit. I told my dad that my mom was miserable and it was unfair to make her live without central air conditioning when the outdoor temperatures are in the 80s. I told my dad that if he did not replace the machine, that I would call someone and have the work done in the middle of the day when he was out. The next day, my Dad decided to call the HVAC business in town to make an appointment.
