You should try Paris. Now THAT is what I call depressing - filthy as shit, smells like pee everywhere, no AC (in most trains), full of pickpockets, homelessness and beggars (including tons of children), grey, takes forever to change lines, no elevator, no toilet, NO ESCALATOR, and some stations/lines are so dangerous that the locals would tell you to avoid them etc. etc. etc.
And the London tube manages to out-depress this Parisian mess by charging everyone a fucking fortune. SMH.
Never been to New York though, and from what I’ve heard it’s even more disgusting than Paris. Ew.
