Ramblings

I'm sick of hearing "But the decade starts in 2001 so it ends at the end of 2010!" Stop it. You are pissing everybody off.

You may argue that 1900 was part of the 19th century, but you can't argue that it was part of the "eighteen hundreds." Similarly, 1990 was part of the "nineties" and not the "eighties." It is therefore popular convention to group decades as the 10 years from years ending in 0 to years ending in 9.

That is all.
