I love the West Wing but it bothers me that in season 1 Zoey is 19 (when she started college) then at the end of season 2 when her starting college became a plot point she was retroactively made younger to be 17 when she started college.

It bothers me that in the first episode Bartlet mentions his 12 year old granddaughter Annie, then 5 seasons later she was starting High School. Then in season 5 she is shown clearly much younger than 19.

I hate it when they do shit like this with TV shows.
