Like around 10pm or 11pm or so I'm walking back to my back alley cottage from the downtown area a few blocks away, and I see a major busline coming down a side street, and I think to myself, "That's odd," and then I wonder if it always turned there, but I just hadn't noticed.
Then, I get up to the main east-west drag, and there's an ambulance down in front of an apartment building, and I can see down past that onto the parallel street, and there's a bus going down that in the other direction, and I realize that there must be some kind of sudden re-route going on.
And, I see a (mid-20s) (fat) (white) girl at a bus stop just beyond where the ambulance is, and she's looking at her phone, and so I call across the street to her to let her know that there seems to be some kind of a re-route going on, and as she's like, "Oh, that's why the bus should have been here by now!", I see a small van with the local transportation agency logo on it putter by, probably to check out what was happening and if they needed to set up signs or something.
