To think people are shockingly rude/entitled these days?

[Troubledee]

There’s so much rude and entitled behaviour around these days and just this weekend I have encountered lots:
A woman sat with her legs to the side on a tram as she was looking behind her. A few minutes after I sat down she turned her body round even more which resulted in her legs digging into mine. She must have been aware of this.

On a bus yesterday a man had earphones in but the music was so loud everyone could hear. To add he was chomping on an apple and his slurping and slapping of his mouth made him sound worse than a dog eating.

I am now on a train and have a lady and little girl sat on her lap. The little girl has an iPhone with a nursery rhyme really loud on repeat. If it was quiet, fine, but it’s not.

The amount of times I hold a door for the person behind me and don’t get thanked.

People are so very rude! What happened to manners?

I'm on holiday with family where more family have come out to stay. The DC seem to be (literally) unaware of basic manners like saying please and thank you, asking to be excused from the table, eating with mouth open, interrupting, saying excuse me rather than just pushing through past someone in a tight space to get to their chair, taking turns etc, helping to carry bags in from the car, not splashing others seated around the pool, not offering up their chair to (frail) granny etc. I realise I sound like a hideous judgmental cow saying all of this but I like children generally and these DC are intelligent and curious and I like them a lot, but I worry how they are going to get along in life without being taught this basic awareness of others.
