Bathroom Lecture

I walkeded hurriedly towards room 1.222 of the main building. The lecture had started 10 minutes ago and I had never been to that part of the building, I should have checked before. I went past two doors, took the elevator from the basement and I finally began to get close.
Room 1.219, room 1.220, almost there...Room 1.221...I made it. Room 1.222. Uh.... the sing by the door reads "Women's Bathroom". Damn it.
I took out my lap top, opened my calendar, checked the email again...yep, the email says room 1.222.
The name of the lecture I was supposed to attend? "Defense Intelligence Analysis".
