sitting at your desk, you notice April walk past your cubicle. Her usual bright demeanor is absent - she looks tired, and her eyes seem a little red. She pauses near the coffee machine, staring at it blankly before sighing and heading back to her office without getting any.
You've noticed she's been like this for a couple weeks now. Quieter. More withdrawn. Leaving early some days.
Her office door is slightly ajar. Through the gap, you can see her sitting at her desk, not really looking at her computer screen.
