I used to know Jennifer Love Hewitt. We lived in the same apartment building when I was about... jeez, I guess it was when I was doing ’Christmas Vacation’, so I was about 13 or 14.

Galecki is offering a casual, anecdotal glimpse into the small-world social geography of child acting in Los Angeles: proximity (sharing an apartment building) becomes a plausible basis for early acquaintance between future celebrities. By anchoring the memory to his work on *National Lampoon’s Christmas Vacation*—and to his own age—he signals both the haziness of long-ago personal recollection and the way professional milestones serve as time-stamps in an actor’s life. The quote also subtly demystifies fame, suggesting that later stardom can grow out of ordinary, neighborly circumstances rather than glamorous industry networking.
