Thanks. I finally got around to checking what are the "definitions" for each of the labels. I didn't even know about Gen Alpha and Gen-X. I just know I am a millennial, my parents are boomers, and the people that I don't understand are Gen-Z.

I think some people just like labels. My wife loves talking about her being INFJ. I still don't remember my letters, even though I did the test, and she knows my labels. She got annoyed once by the fact i did not remember, but then suddenly accepted it when she read somewhere that INFJ care about the letters while my subgroup is known for not caring about the letters.
