If you walk around the grounds of South Pasadena High School, you'll see these tiles embedded all over the place. For years I tried to figure out what they meant. Was the architect an obsessive compulsive who really needed to count? Were the numbers a reminder of South Pasadena students' reputation for great math skills? Did the entire sidewalk design come out of a big Tile By Numbers box? Was it a horrific reminder of the relentless, unending passage of time?!
Eventually, Mister Earl told me the numbers represented graduating classes of the high school, and that every year was (or would be) represented.
I like my obsessive compulsive story better. (All together now: one, two, three, four... ahhh. I feel better already.)
