Always "yes please" and "no thank" you for me! Though my parents tried to make us use "ma'am" and "sir" as kids. It never stuck, though my maternal grandparents are from Kentucky. The grandparents call us "ma'am" or "miss" all the time.
I'm the least generation Z "zoomer" you're going to meet. I'm 20, married, financially, spiritually and mentally stable and expecting a child, if that gives you a good enough idea. Others in my generation (usually the ones that are my age or younger, not the much older ones) tend to annoy me with their relative lack of intelligence and aversion to objective truths and reality. Too much social media, too much "affirmation" making kids go soft. Gen Alpha terminology? Drives me up the wall and makes me feel like an old grump. "Arg, have you no shred of respect for yourselves or others, *
grump grump grump gnashing of teeth*".

Actually, most of my views about "kids these days" make me feel like an old grump!

Makes it a bit difficult to make friends of similar mindsets. I was also homeschooled, so that probably explains a lot, lol. Can't wait to see how different my kids turn out than the rest of gen Beta.
ALSO, I grew up in Ohio, and it's way better than almost anywhere that I've ever visited. So keep hating Ohio, because Ohioans are glad to keep it to themselves!
