You know you're getting older when. . . .

. . . you forget that you had a depo this afternoon--even though it is the only thing on your calendar and was only scheduled last week--and wear jeans to the office.

. . . your (same-age) friends' children are in high school or college.

. . . you decide you need a new pair of low-heeled black shoes for work and find yourself gravitating toward brands like Naturalizer, Hush Puppies and Dr. Scholls.

. . . the music you grew up listening to is on the "oldies" station.

. . . the styles you wore in junior high and high school have made a comeback.

. . . when you hear of anyone under the age 30 getting married or having a baby, you think "But s/he's so young!"
