As technology and the rest of the world evolve, societal rules follow.

“Wearing hats indoors.

Not going to lie, it still bugs me.”

A man in casual attire, including a cap and hoodie, is holding a shopping basket full of groceries in a supermarket aisle, reading a list

“Back then, it was very rare to question the authority of teachers.

I often read stories from teachers and am kind of shocked by how students treat their teachers these days.

Also, back then, parents rarely intervened if their kid was disciplined or received a low grade.

Two people, name unknown, posing and smiling in pajamas inside a room. One wears a red sweatshirt and patterned pants, the other a pink tank top and pajama pants

According to teachers, parents get livid when their darling, special angel is reprimanded in any way.”

“Wearing pajamas out of the house.”

Two women chatting in a coffee shop, one holding a small white dog

It seems acceptable nowadays to thank people in person or with a shared post/photo/text.

I’ve accepted that.

I have relatives who don’t even acknowledge that they’d received the gift, let alone appreciate it.

An older man and a young woman relax on a sofa. The man in sunglasses reads a document, while the woman in a plaid shirt leans over to look

That is not cool."

“Being loud in a waiting room.

“Talking at the library.

When I was younger, libraries were well-established as places for peace and quiet.

A teenage boy sits on a subway, engrossed in his phone. Other passengers are also absorbed in their devices, creating a sense of individual focus in a shared space

Now, people talk regularly and even listen to music on their phones without headphones.”

People feel ridiculously comfortable doing that now.”

“The ‘not responding’ thing has gotten bad.

It’s so disrespectful and treated as okay behavior now.

Yeah, I may be old, but the word makes me bristle.

Why not just say, ‘I need to use the bathroom?'”

“Not giving up your seat on a bus for an older person or person with a disability.

People would’ve chastised somebody who didn’t do that 40 years ago.”

“Offering one’s opinion without being asked for it.

Now, people feel entitled to spout their opinions on unasked subjects.

And God help you if you disagree.”

Now, it’s considered rude to not immediately respond to calls, texts, direct messages, etc.

Anyone who thinks that’s rude isn’t someone I want dealings with.”
