Learn From My Mistakes: Day 3 - Numbers

I'm very bad about spelling out numbers, especially time.

It's six o'clock, six a.m., and after six that evening.
Years are spelled out (eg: nineteen sixteen, not 1916, unless...see picture at left.)
She was eleven years old, not 11.
It's our fifteen wedding anniversary, not 15th.

I think what screws me up is that there is so much inconsistancy regarding spelling out numbers in the books I read. I've seen it both ways, and that makes me wonder about the editors.
