Dear Diary. Girlfriend and I are eating dinner. I am in a bad mood due to tiredness. I try to stop myself from snapping at her. I start to think it has been a mistake to take the night shift.

Girlfriend shows me apartments on her laptop. This frustrates and bores me. For the past month, she has shown me several apartments a day. She expects me to consider each one carefully then give an opinion. I wish she would take initiative and call to arrange viewings herself. As she talks, I close my eyes briefly. It feels nice, like I could fall asleep. Girlfriend notices I have my eyes shut. She gets up from the sofa, annoyed.

I go swimming. The cold water feels good. Refreshing. I am back to myself. When I get home, the bags under my eyes scare my flatmate. She says, "You look really tired.” She stares at my eyes, amused and in wonder.
