In my own mind, I like to pretend that I'm a very consistent person when dealing with others - always social, smiley, and go lucky; even when, internally, my mood can be swinging like a pendulum.
But I also know that I wear my heart on my sleeve, and emotions on my face. People seem to read it easily.
Like when I'm troubled by something, my brow gets all furrowed, and I get all quiet. Even though it has nothing to do with my current company, they see it.
Knowing this, I suppose I shouldn't always expect other people to always have the same demeanor when dealing with me; and I can't possibly be expected to always know why someone has a change in demeanor. So I shouldn't take it personally if it does happen.
Ok, diary. Thanks for helping me think this through. Back to work!
