Lunchtime conversation with a cashier at Au Bon Pain:
Me: (silently places food items on counter)
Cashier: (looks at me penetratingly) Hungry? Exhausted?
Me: How did you know?
Cashier: Your eyes have that look. Go eat. Get some rest.
Me: (having read/watched too much True Blood, wondering if cashier can read thoughts) Thanks--I'll try.
