When is a Wednesday...?

It's a tricky week. The kids are back at school. It's raining. It's cold.
People come, but not in numbers.
There is a silver lining.
It means I get to read the Teme Valley Times.
A pile of TVTs started appearing at the tea rooms as if by magic this season. I never see anyone arrive with the bundle of them. Someone leaves them on the side table in the conservatory and then disappears without even a mention.
The paper is remarkably popular. Often a couple will grab TWO copies on their way to their table and are engrossed when their tea is delivered.
I haven't had many opportunities to go much beyond the front page until this issue.

On page 3 is a piece about the local jobs bus not arriving at its designated spot when it's meant to - that is one Wednesday a month.
There's a 3 paragraph preamble about it and then this, which I re-read four times:
"Early this year the Teme Valley Times received complaints that the bus wasn't turning up. We have finally got to the bottom of this. The key is simple: the bus does NOT come on the 4th Wednesday of each month. For example, during the first three months of 2011, the bus came on the 4th Wednesday of January, and it came twice in March (but not on the 4th Wednesday) while it didn't come at all in February."

I haven't got further than page 3 yet.
