At my job, there is plenty of "ass time" -- time spent sitting and waiting for something that requires my attention or participation. In a 12-hour shift, I'm lucky if I spend 4 hours actually doing something. I have a few computer monitors at my desk, and the majority of my shift is spent monitoring the data on those screens. There are things I can do out on the production floor, but not many, and not very often. Welcome to mill work.
Anyway, we're not allowed to bring laptops (or books, for that matter) to work, so that ass time can stretch into boredom very easily.
When we're on night shift, I can stare at my phone, which I do a lot of, but even that gets boring after several hours. My solution to this is journaling. I keep a notebook in my locker, and every day I bring it into the office and set it under one of my monitors. When the urge strikes, I grab it and start writing whatever is rattling around in my brain. Quite often, the subject of crossdressing comes up.
Ah, but there's the rub!
I work in an office with 2 other "techs," and various people popping in and out throughout the shift, especially when we're on day shift.
It wouldn't do to have my coworkers reading my journal and discovering my love of nylons, dresses and all things girly, since nobody at this job knows about this side of me. So, I have to be very...diplomatic (read "sneaky") with what I write in my notebook. I can't mention dresses, so I call them vestidos (Spanish) or Robes (French). I most certainly can't mention pantyhose, so I call them medias (Spanish for socks) or Collants (French for pantyhose). I absolutely can't write about doing all the gay stuff I fantasize about doing, so I have to refer to those activities with vague or cryptic language. If anyone were to peruse my journal while I'm away from my desk, there is a very low likelihood that they'd understand what they're reading, at least the full context of it.
While this works to keep my freakier inclinations undiscovered, I would honestly prefer that everyone just know I'm a bisexual crossdresser and write what I really want in my notebook.
Maybe some day. Not today.
So for now, I write in foreign languages and my own little code.
