Well, North Americans do sometimes write 31st of December, 2011 as 12/31/11 or 2011-12-31, so it might have been a fair question
Indeed. Listen up North America:
28.06.11 = Fine
11.06.28 = Fine
06.28.11 = INSANE
Or perhaps I've missed a million other examples where formatting is done out of ordinal sequence?
Any sequence where month and day can be confused = insane. It goes : day, month, year. How hard is that. Don't blame the metric system either, it's just common sense.
At least the guy didn't steal your bike too. It's something.
