Usually when people get older and start complaining about new "unpleasant people" the issue isn't that new unpleasant people exist. Rather, its that the older person has not adapted and is stuck. They become "get off my lawn" types
As someone who is 32 and takes public transport, if a homeless person gets on my train car and smells bad enough to stink up half (or all!) of the car, they have earned the "unpleasant people" label fair and square. Yes I understand it may be their only option, and I sympathize with them but it still makes my trip unpleasant.
It is, but it's also just something I see time and time and time again.
Every generation complains about how the world is going to shit and the yougins ain't got no respect and whatever particular segment of brown people at that time don't belong in their country.
I would have some sympathy if this wasn't, like, the millionth time this has happened.
