I worked to keep a smile on my face as the noise increased around me. It was getting harder to focus on the conversation at hand, my eyes wanting to dart to every movement I could sense from the corner of my eyes. 
It wasn't usually this bad.
Not usually.
But I had had too much stimuli recently and it was making me twitchy. Jumpy. I had to...I had to "I'm sorry, I got to go." I said abruptly, standing from my seat. I needed to get away from this place and it's constant distractions.
