There is no secular/logistical miracle that is more heatedly bitched-about than New York City's subway system. It runs all the time, more on-time than not, through -- and mostly under -- a large and difficult city. And yet the one time there's a moderate sized rat running around on an A train -- the one time -- everyone freaks out.
To be fair, this is a perfectly reasonable response to a rat on the subway, or anywhere else. They're hideous, although this is of course their city, too.
I have lived in New York and ridden these trains for 13 years, during which time I have seen rats frolic and hump and attempt to eat what appeared to be a child's mitten, which was lying in a puddle on the tracks. I once watched a rat roughly the size of a plumper-than-average Yorkshire terrier go downstairs at the 86th Street 4/5/6 station, effectively transferring from the local to the express. These things happen.
This is, admittedly, the first time I've seen a rat ride a subway from Manhattan to Brooklyn, which was honestly fine by me. If you've seen this, or something roughly this hideous, feel free to share in the comments. We will get through this together. Get through it or start taking the bus everywhere.
