Narrative:

In cruise and time for a bathroom break. Ladies first; 'I have it' oxygen selected and on; my senior first officer got up; opened the door and walked out! Only the flight attendant wasn't given a chance to walk in the cockpit before the door was closed and locked! I chimed the chief purser. You have to understand; my first officer is very senior and almost exclusively flies europe with 2 first officer's and a captain; so she just forgot about the 2 person rule and when she did; it was too late. I called her on the interphone and confirmed that it was clear before I let her back in with some difficulty. All was well and safe but I sure did feel suddenly alone and I was just about as surprised as my fine first officer who couldn't have been more apologetic and sorry. I suspect that she won't make that mistake again.
