At work, we'll soon move to our new San Francisco office. But for now, we're in a co-working space in a mall. In the morning, I walk through the mall. It's not open for business so early, so it's nearly empty. But it's not quite empty and it's rather echo-y. So I walk through this cavernous space while listening to echoes of a far-off janitorial cart. It's unlike other places I worked and I wanted to make sure I remembered it before we move.
