A friends daughter just finished 7th grade today... I can remember long worried rants from him while she was an infant.
My "little" sister Tricia (actually my stepsister since she was 12) Turned 27 the other day.
Most of the "kids" I went to high school with (many of whom I have known since they were 5 years old; having attended high school in the same town I attended kindegarten) have kids of their own, some of them in high school themselves now... in fact, a couple of them even graduated this year (I finished high school 19 years ago).
Time passes.
