Working from a coffee shop is a great way to observe people, their actions and interactions. I look around at other people working on their laptop and what I notice is how many people frown while working. The furrowed-brow look.

There’s the pensive frown by the aspiring writer while she tries to place the lead character’s sequence of events into the overall story arch.

There’s the corporate rung-climber with his intense “I’m so busy with difficult, important work that has to be ready in an hour for my next exco” frown.

Then there’s the caffeined-up internet troll, angry and affronted by the world and living in victim-hood, scowling into his screen.

So many emotions. So much expression. The human animal is a fascinating species.
