Heidi called

One of the funny things about Japan is that they use a completely different phone standard than the rest of the world. So I was without cell phone coverage since Monday.

When I turned on my phone here in Shanghai, I got a whole mess of missed calls. I noticed that Heidi called. Once, Thursday afternoon pacific time. She left no message. No text. No other apparent attempt at contact.

Hmmm, what's the protocol here? Do I call her back? I'm thinking not.
