The MTA had been behaving itself for a couple of months (inasmuch as it ever behaves—the 8, on the occasions I’ve had to use it, has been as bad as ever), so I suppose it was due for something.

The 31 scheduled for 6:58 at Liberty and Baltimore never arrived.  I waited until roughly 7:20 before a 31 came by.  (The next scheduled arrival was 7:24.)  The bus then sat at the Arena stop for roughly 15 minutes as the driver waited for a replacement.  None was forthcoming, so he eventually drove on, despite the fact that he was supposed to have been relieved.  I got home a bit over an hour later than I ought to have.
