I’ve lived in the southern US a good portion of my life, where a lot of parents go by “sir” and “ma’am” and you are expected to call others in public as “sir” and “ma’am” respectively. So, while I see what you’re saying, the father in this case may agree unironically.
I wrote “2018” as the date the other day and it took me quite a while to realize what I had done. I’m 29. 💀
