What if Schwartz no-shows?

What should you do when Prof Schwartz does not show up at class start-time?

Who you gonna call, Ghost Busters?

Call my office phone instead: 650-574-6389 while you’re waiting for me.

If I am having trouble getting to our class, I will forward my office phone to my cell phone, so someone in the class can call me and find out whether or not I will arrive soon enough. (If I cannot make it, you won’t have to wait around to find out the hard way.)
