Pretending to repair the A/C

My sister and her husband wanted to go out 1 night, so I offered to babysit their little girl, my niece, Jen, however jen and I decided that the people I was with and I were going to play HVAC repair corporation, she had myself and others pretend to call the HVAC dealer and ask for someone to come over and help with the AC.

She wanted myself and others to say that it was really tepid in her house and that she needed someone to come out ASAP to take a look at the AC, then the A/C was not absolutely broken however she wanted myself and others to pretend, then i thought that this was a strange game for a 4 year outdated to want to play, but I went along with it.

The two of us played pretend HVAC repair shop for a few hours that night, and she was finally able to repair the AC! Of course, Jen wanted to be the HVAC repair man, and when my sister got home, she asked what the people I was with and I did. Jen was asleep but I explained that most of the night was spent pretending that the HVAC system was broken and not to worry, that Jen was able to repair it, but my sister laughed and said that their neighbors had their HVAC worker over the week before and that’s where she got the idea. I thought it was so cute that she was wanting to play pretend HVAC. What 4 year outdated girl wants to spend her night prenteing to repair the AC?
