Coincidence

Over pizza a few days ago, I said to Lut, "It's not 'twice is a trend', is it? It's three times. 'Once is a fluke, twice is -- something? -- three times is a trend'."

Lut considered that. "'Once is an accident, twice is coincidence, three times is enemy action'," he quoted.

"Yeah. I suppose the non-military version would be something like 'once is a fluke, twice is coincidence, three times is a trend'. Twice isn't necessarily a pattern."
