Old ticket stub reminds me of my father

When I was cleaning out my attic space, I found an old coat that I used to wear when I was younger.

I searched the pockets and I found an old ticket stub.

It was a concert I went to with my father when I was younger before he passed away. It actually made me feel emotional. I was there for the music, but I remembered how my father kept talking about how remarkable the HVAC system was in the venue. It was genuinely a large stadium and the place was air conditioned just right, regardless of how many people were in there. He remarked that those industrial HVAC systems must be extremely efficient to keep such a sizable place so cool and comfortable. I thought that was foolish talk at the time, but now I agree with him that it was impressive. I miss everything about my father and it’s a shame that we are no longer able to hang out like how we used to. There was this one restaurant we used to go to where they had a really nice HVAC system. The boss showed us the smart app on his phone and how he adjusted the temperature control settings with it remotely. Now that really impressed my father and he had to run out and get a smart thermostat as soon as he could. I actually helped him to install the smart thermostat, and we were so happy when we finally figured out how to get it to work. Man I tell you, those were the days.
