i am stupid

I left my laptop bag in one client's office, and she locked up and went home for the night while I was working with someone else, so I'm wandering around their building looking for the maintenance staff.

I tell my problem to a couple of women in the break room -- they promise to keep an eye out for the custodian. I keep wandering, until finally I see his cleaning cart outside the women's restroom.

I crack the door and call "Knock, knock!"

But instead of the custodian, I hear one of the women I had just talked to sing out "Uh oh, girls in here!"

Then since she apparently recognized my voice, she says "Hey there's a guy waiting for you at the elevator!"
Terrific, I think. She's found the custodian and sent him to find me. So I go wandering around the elevator area, taking it up/down/up for a few minutes, checking each floor.

Eventually it comes to me that I'm looking for myself. When I talked to her outside the restroom, she hadn't recognized my voice at all -- she had assumed I was the custodian, and was informing me that some bozo needed an office opened.

Feeling sheepish, I decide I might as well just leave and get my bag in the morning. I went back to the office I had been working in to retrieve my jacket and papers.

There I find my laptop bag under the desk, where I'd forgotten I put it earlier.
