I'm a Xennial, born in 1980. I have traits of both Gen X and Millennials, but not the entirety of either.
Examples:
I have the grungy cynicism of Gen Xers, but also the positivity of millennials. But my maturing experience didn't involve Gen-X's drug-fueled raves or the social media dating and shaming that millennials had to navigate.
I remember my parent's 8-track collection, made my own mixtapes (and later mix CDs), memorized the phone numbers of my friends, and used a rotary phones.
I was fine using a T-Mobile flip-phone until 2015, and could go back to using one without feeling like I'm missing anything essential.
I was a Hulkamaniac, loved the Ninja Turtles and Duck Tales, I got my first NES at age 8, and had a Walkman in high school.
I remember watching Star Trek reruns on my dad's lap, and watched the first episode of The Next Generation on a beanbag chair. I watched every episode from every series pretty much as they aired from Next Gen through Enterprise and loved every minute of it, but can't stand anything from Discovery onward and have almost given up on the franchise.
I was latchkey and got my first job (and first car) at 16. I didn't take college classes until my late 30s because there was no need to do so, and only then to get a higher paying job in the same field.
I'm as equally comfortable taking notes in cursive as well as typing them into my phone. I can use a Rand McNally (and fold it up again) just as easily as I can use Google Maps.
I can do vehicle repairs from a Chilton's or follow a YouTube vid - whichever one seems to be more accurate for the job at hand.
I watched technology go from no computers in anyone's home I knew as a kid, to doing basic CAD stuff and being the only person taking a typing class on a PC in my freshman year, to having a job that involves working with AI and data analytics.
My coming of age highlights include the Mortal Kombat movie, Saving Private Ryan, Lord of the Rings, Chumbawumba, Ace of Base, Blues Traveler, Smashing Pumpkins, Tool, Offspring, Final Fantasy VI (labeled as III in the US), the release of the Playstation, Everquest, and the World Trade Center.
I'm pretty modern. But in a very real way, I never left the 90s.

I like to think that I got the best of both the Gen-X and Millennial experiences.
