In a conversation with the cab driver on my way home tonight, we both commented on the rain outside. I then said, “But it must be a good night for taxis.”
He replied, “Yeah, rain is good, but it’s the slow time of the year.”
“Oh really?”
“Yes, everybody spends too much during the holidays, so they stay in.”
“Good point.”
“It’s slow for the next month and a half.”

Seems logical now that I think about it. Even taxi cabs are seasonal.
