Thank goodness I have an elevator! Mimi and I use it many times a day to go outside. There's an annoying little lobby at the bottom of the elevator, though, that we have to walk through to get outside. Some neighbors park their e-bikes in the lobby, instead of parking them one more floor down in the basement where they have ramps for easy in-and-out access. We have to squeeze by them to go in and out. There are signs in the lobby that say "no parking," but those signs have been there eight years and no one enforces the rules. In the photo above, Mimi and I have just come back inside the lobby from outside. We entered through a clear glass door that we have a key to.
The lobby is L-shaped, and we've just turned the corner of the L. There's the elevator on Mimi's left side. The lady from the 9th floor lets her brown male poodle pee at the very bottom of the stairs every single day (you can't see the stairs, but they are to Mimi's right side). People walk through the pee because they don't notice it until it is too late. Mimi, on the other hand, swings way out so she doesn't get anywhere near the puddle.
Two families have first floor apartments. I wouldn't want to be them, with people right outside your door all the time waiting for the elevator.
All my neighbors used to be afraid of Mimi, because she barks loudly at them. Most of them have gotten used to her and laugh at her now. They know she's not going to bite. Maybe they don't all love her, but I'm not really thrilled with all their e-bikes and dog pee either, so we're even.
In China, public areas like lobbies and stairwells are not well maintained. We have cleaners who come every morning with a wet rag mop. They go up to the 10th floor with the wet mop, and walk down the stairs mopping as they go. They never clean or re-moisten the mop during this routine, and things don't get very clean. The walls are black where the dirty mop slaps them when moving from side to side.
Even very rich people live in this kind of environment where they have to put up with less-than-stellar public areas. What I mean is, I think the people on the 10th floor of my building, who have two floors and roof garden access and drive BMWs are probably millionaires. They have to deal with the dirt, clutter and dog pee just like us regular joes do.
I travel to Shanghai via high-speed train. Here's a look at the train station platform.
