Like Bruce Banner or Dr. Jekyll, I think each one of us have a Hulk or Mr. Hyde within us. Though in majority of the cases we don't turn into a jacked up green monster nor a evil and violent man. Some of us act differently between various groups of people whether that be at work, friends, and family. While I tend not to do it, I can see why others often do; this being because the chemistry and demeanor of the group, previous experiences together, etc. Sometimes, it's just certain "ticks" that initialize certain behavior.
Yesterday, I was once reminded of my enabler for different behavior which is competition. Last night while playing in a volleyball tournament, I became aniMATTed. If you don't know what that means, it is when I lose control of my "indoor voice", which results in the use of the voice volume I learned at UConn sporting events (beyond loud) making sounds that may or may not be words. It also involves quite a bit of hand movements too including tumultuous claps and slapping the ground. And the body movement is... Chaotic. That's probably the best way to describe it; between points I can be laying on the ground, jumping up and down with joy or frustration, just standing stilled, or just sitting Indian style.
This behavior, of course, differs from my calm and cool demeanor during the rest of the time.
What makes you behave strangely/differently?
