Discreet Discretion

Until fairly recently, I did not know that "discrete" and "discreet" were two separate words.

Discrete means "distinct or unconnected," as in separate: discrete definitions.

Discreet means "unobtrusive; able to keep things quiet," as in "MWM seeks same for discreet daytime play."

This knowledge came from a Craigslist personals flame to which I was an observer.
